In plant cells, sunlight plays an active part in photosynthesis, which helps a plant grow. In human cells, sunlight stimulates the activation of vitamin D in your body. The term vitamin D actually refers to a group of steroid molecules. Vitamin D3, also known as cholecalciferol is generated in the skin of animals when light energy is absorbed by a precursor molecule 7-dehydrocholesterol. Vitamin D is thus not a true vitamin, because individuals with adequate exposure to sunlight do not require dietary supplementation. There are dietary sources of vitamin D, including egg yolk, fish oil and a number of plants. The plant form of vitamin D is called vitamin D2 or ergosterol

In simplest terms, photosynthesis is an anabolic pathway and uses light energy to generate ATP which in turn is used for biosynthesis to make glucose storing the energy derived as glucose. It also consumes CO2 and produces O2. While respiration is a catabolic pathway deriving energy from complete metabolism of glucose to CO2 and water using oxygen in the process.

The short version: light hits a pigment molecule, like chlorophyll, and boosts an electron to a high-energy state.  That high-energy electron is then used to jam the phosphate group onto ADP or NADH.

By capturing the light and storing it.\nFor example capturing the sunlight inside the glass chambers filled with special metal foils that will get heated and then can be used later in solar energy.\nSo, that we can use that energy to heat, light, cook, and many other things.

oxygen, because they need it for cellular respiration, just like we do.  In order to use CO2, sunlight has to be present.  Therefore, they don't use CO2 at night.

You are probably referring to metabolism.  Metabolism is a collection of chemical reactions that takes place in the body's cells to convert the fuel in the food we eat into the energy needed to power everything we do, from moving to thinking to growing. Specific proteins in the body control the chemical reactions of metabolism, and each chemical reaction is coordinated with other body functions. In fact, thousands of metabolic reactions happen at the same time - all regulated by the body - to keep our cells healthy and working.

Sunlight is necessary for plants to grow, and to provide energy to warm the earth's atmosphere. Light intensity controls plant growth. Light duration affects plant flowering and animal/insect habits.\n\nNow, during photosynthesis, sunlight energy is used to power chemical reactions that combine water with the air's carbon dioxide to form starchy carbohydrate. In other words, during photosynthesis, sunlight energy is stored in carbohydrate for later use. Here's the simplified chemical formula for photosynthesis:\n\n6CO2 + 12H2O + sunlight ---> 6O 2 + C6 H12O 6 + 6H2 O\nor...\ncarbon dioxide + water + sunlight ---> \noxygen + carbohydrate + water \n \n\nSome carbohydrate remains in the leaf but mostly it's transported elsewhere in the plant, perhaps into the stem, or maybe into special underground storage areas, such as the potato plant's potatoes.

Most life on Earth is powered by the Sun. Plants use Photosynthesis to make carbohydrates from the Sun. Animals eat Plants, we eat both plants and animals that eat plants. Therefore indirectly virtually all of our food energy comes from the Sun. Our Brain uses our food energy to operate. Therefore our brain is powered by the Sun.

Photosynthesis generally takes light, CO2 & water and makes sugars.  These sugars are chemically converted in to food, propane, methanol, ethanol, coal, oil, wood and all the other fossil fuels and orgnic compounds on the earth, through natural, geologic, and/or manmade processes.  At every step of each process, energy is lost.  To gain usable energy, other than in biologic processes, requires burning something, and using the expansion of heated gases to create physical force (motion), or then using physical force to drive a generator to create electrical current.    \n\nWe do not currently have an effecient method of making electicity using incoming Solar radiation.  Current solar cells convert a small percentage of one section of the electromagnetic spectrum into electric current.\n\nHope this helps.

You should do an experiment, that's what i did.\n \nPhotosynthesis is the production of food compounds from carbon dioxide and water by green plants using energy from sunlight, absorbed by chlorophyll ie. photosynthesis is how plants feed.\n\nlightlightlil\n\n6CO2 + 6H2O                 à C6H12O6 + 6O2\n\n        Raw materials   Products\n\nie.         Green plants make organic substances from inorganic substances.\n\nIn order to keep the equation for photosynthesis simple, glucose is shown as the only food compound produced. However, this does not mean that glucose is not the only food compound produced.\n\nThe process of taking in and giving out gases is known as gaseous exchange. When green plants photosynthesise, they take in CO2 and give out O2. This only happens in daylight when light is available as an energy supply. The exchange of gases in green plants in light is the opposite of that of animals; however this does not mean that green plants do not respire. During daylight, plants photosynthesise and respire at the same time, hence all CO2 produced by the plant during respiration is transformed into O2 and food (and thus energy) for the plant. It is only when the rate of photosynthesis is greater than the rate of respiration that CO2 will be taken in and excess O2 given out.\n\nie.         In darkness O2 is taken in and CO2 is given out - there is no p/s; in dim light the rate of respiration and p/s    is equal - there is no gaseous exchange with the air; in bright light however p/s is faster than respiration          and thus O2 is given out - CO2 is taken in to use for p/s and the CO2 made from the plant’s respiration is   also used to make O2.\n\nie.         The more light (the higher the light intensity), the greater the rate of p/s - unto the LSP [see below].\n\nIf a plant is given plenty of sunlight, carbon dioxide and water, the limit on the rate of p/s is the ability of the plant to absorb these materials and make them react. (eg. total number and capacity of chloroplasts and the physical limitation of carbon dioxide diffusion.) Most of the time plants DO NOT have an unlimited supply and so the rate of p/s is not as high as it might be.\n\nBlackman’s Law states that:\n\n            “The factor in least supply will be the limiting factor.”\n\n\n\nAs the light intensity (LI) increases, the rate of p/s increases, until the plant is photosynthesising as fast as it can - the LSP - Light Saturation Point. When the LSP is reached, plants cannot photosynthesise any faster, even when the light gets brighter. From this point on, according to Blackman’s Law, the factor in least supply will be the limiting factor ie. either CO2, H2O or temperature will be the limiting factor.\n\n\n\nAs the amount of CO2 available increases, the rate of p/s increases, until the plant is photosynthesising as fast as it can - the CSP - CO2 Saturation Point. If both CO2 and light supply are increased together, the rate of p/s will level out. Henceforth it is limited, according to Blackman’s Law, by the factor in least supply, either H2O or temperature. however there is a physical limitation of the carbon dioxide diffusion and the plant’s sunlight absorption.\n\n\n\nAt a lower temperature, the rate of p/s is increasing with increasing LI or CO2 availability, but the LSP or CSP is quickly reached. At a higher temperature, the rate of p/s increased further and reaches the LSP / CSP slower. Thus we can se that temperature affects the rate of p/s - it is higher at higher temperatures.\n\nFrom this information, one can see that if one wants to investigate solely the effect of the quantity of light on Elodea, one must keep both the amount of CO2 and the temperature constant.\n\nLight intensity will decrease as the distance between the light source and the object increases, and vice versa.\n\nThus the relationship between LI and distance can be described as\n\n         1 This value will be very small; multiplying the LI 1000\n\nLI =

I'm always happy to help out a Van Halen fan! Anyway, photosynthesis is the process by which plants convert sunlight into energy and fuel to grow, and also to manufacture proteins, the most important of which is chlorophyll, which gives plants their green color. They also convert this light into sugars anfd starches, which they need to grow. (The storing of these sugars, in fact, along with the slowing down of the photsynth, is what gives those autumn leaves their great colors.)  During the dark hours the plants are basically dormant, and thus no photosynth taking place, but they are still respirating, i.e. taking in carbon dioxide and releasing oxygen. They do this in light too, of couse, but at a faster rate. But just like we need our sleep, the plants need the dark also to rest and store their food, otherwise they would expend it all and thus dry out, which is why they get yellow (depleted chlorophyl) with too much sun.

The answer is (D) simple sugars.  However, cells must break down glucose through cellular respiration (glycolysis or fermentation) to create ATP, which is the energy molecule used for cell processes.

ok so packets of sunlight are called PHOTONS and those PHOTONS are absorbed in PHOTOSYSTEM 2 (PS2) which are proteins on the membrane of cytoplasm cells on plants (or any photosynthetic organisim)\n\nfollow so far? ok here is where it complicated...\n\nok so little electrons are floating around in PS2 and when the light comes in it energizes them and they zoom across into PS 1. and are now PHOTON ELECTRONS.\n\nmeanwhile....\n\nwater (h2o) is also being absorbed and the electrons are splitting them apart so it is just an h and an o. so the o goes away somewhere and the h floats into the PROTEIN SYNTHASE which is also a protein in the membrane of cytoplasm. it is shaped like a tube. when hydrogen goes in, it spins and produces ATP. \n\nBUT...\n\nremember the PHOTON ELECTRONS?? they left PS1 and now float arond inside the cytplasm. a PHOTON ELECTRON , NADP+ molecule and ATP combine to form NADPH AND ATP.\n\n\nTHE END!!

Most simply, energy is stored in and carried by ATP and NADPH. \n\nIn detail:\n\nLight first excites P680, the reaction center of photosystem II. P680 gives off an electron, which is then transferred to plastoquinone, then cytochrome b6f, then plastocyanin, then to P700, which is the reaction center of photosystem I. Light then excites P700, the reaction center of photosystem I. P700 gives off an electron, which is then transferred to ferredoxin. Ferredoxin donates the electron to NADP, which produces NADPH.\n\nAt different steps of the electron transport chain described above, protons (hydrogen ions) are pumped from the stroma of the chloroplast to the lumen of the thylakoid. This creates a proton gradient that drives ATP synthesis via ATP synthase embedded in the thylakoid membrane.\n\nATP and NADPH can then be utilized by the Calvin cycle to produce carbohydrates.

mitochondria is a power house because thats where all energy comes from. Sugars and oxygen goes into the cell, into the mitochondria, and the mitochondria burns the sugar using oxygen and, this is the process of making ATP, the energy that cells can use to do work. ull find a lot of mitochondria in muscles and the liver.
