Photosynthesis , basically occurs in two distinct phases. 1) Light reaction & 2) Dark reaction\n            Both are part of photosynthesis\n6CO2 + 12H2 O -> LIGHT &   CHLOROPLAST> = C6 H12 O6 + 6H2 O + 6O2\nThe above is the often quoted equation of the process\n            1) Light reaction or the Hill’s reaction occurs in the grana of a chloroplast.\n  Sun’s light energy is used to convert ADP in to ATP …………. (i)\n   NADP is converted in to NADP. H2…………………………… (ii)\n It can occur only in the presence of light, hence the name.\n2) Dark reaction or Calvin’s cycle occurs in the stroma of a chloroplast.\n   Light plays no role in it. Hence  called dark reaction.\n  With the help of the two products of light reaction, i.e. ATP & NADP.H2 glucose is manufactured from CO2 and H2 O  i. e. carbon dioxide gas and water.\nThe CO2   in the above equation comes from the atmosphere and enters through the stomata on the leaves.\nThe H2 O  in above equation comes from the soil through the roots, stem and xylem elements.\n A single molecule of Glucose (C6 H12 O6) requires all the six molecules of carbon dioxide gas but only 50% of water ( Only 6 out of 12 H2 O molecules entering the reaction (see the equation)\nRemaining 50% water ( The water you are talking about, I presume) and the O2 gas is released back in the atmosphere as a byproduct ( and not waste product) . There is no room for waste in the nature.\nIt is wholly man made and he is paying for that and will continue to pay dearly  for his tampering with the Nature!\n\n\nEdit---> The 50% water that is released in the atmosphere through the stomata comes from the soil...................(1)\n\n              This is recombined water, after spltting of the orginal water molecules in to hydrogen and oxygen to extract electrons \nfor the manufacture of ATP and NADP.H2...................(2)\n\nIn short, all the molecules out of the 12 original are utilised \none way or the other..................(3)

The plants do not 'eat' anything the way animals eat and digest and then defecate.\n All green plants ( with out exception) have unique mechanism of Photosynthesis by means of which they prepare what they want. We, the animals, rob them of the things they have manufactured.In this case Man is more guilty than the other animals as he gives them practically nothing in return.\nThe CARBON in your question is absorbed by them from the surrounding air during photosynthesis. The equation is as follows:-\n6CO2 + 12H2O-> LIGHT&CHLOROPLAST> = C6 H12 O6 + 6H2O + 6O2\nThus carbondioxide gas(6CO2) and water(12H2O) combine together in the presence of sunlight and chloroplst to produce glucose(C6 H12 O6) , water and oxygen gas (6O2). this gas is realeased in the atmosphere!\n The CO2 gas and water is available to mankind easily but can we produce glucose? No way.This reaction will require plenty of energy for our machinary, and the veture will be immpracticable. There in lies the greatness of the Plant Kingdom!\nThe Glucose thus manufactured is then put to innumerable application by thes plants including cell wall formation and DNA synthesis.\n Other mineral requirements are absorbed by them from the soil along with water.\n lastly  CO2 + water in the hands of man = Soda water But\n         CO2 + water in the hands of Plants = Sugar.

synthesis means "combining" or "bringing together"\n\nLight is energy - it provides the energy that plants need to change the chemical bonds of the chemical molecules that are present in leaves into the sugars that the plant uses (and people use) for energy.  Chlorophyll takes the CO2 out of the air and combines it with water to make glucose.  Chlorophyll also contains other molecules and elements, which is why plants are so healthy to eat.\n\nThe chemical formula for chlorophyll is:\nC55H72MgN4O5

* The process begins with the oxidation of pyruvate, producing one CO2, and one acetyl-CoA.\n    * Acetyl-CoA reacts with the four carbon carboxylic acid, oxaloacetate--to form the six carbon carboxylic acid, citrate.\n    * Through a series of reactions citrate is converted back to oxaloacetate. This cycle produces 2 CO2 and consumes 3 NAD+, producing 3NADH and 3H+.\n    * It consumes 3 H2O and consumes one FAD, producing one FADH+.\n    * 1st turn end= 1 ATP, 3 NADH, 1 FADH2\n    * Since there are two molecules of Pyruvic acid to deal with, the cycle turns once more.\n    * The complete end result= 2 ATP, 6 NADH, 2 FADH2

Plants can sustain photosynthesis (and release oxygen) from any lightsource that has enough energy. But plants can also get stressed by too much light and actually get sick. They might also grow in unnatural ways, like growing sprouts all over, if "fed" the wrong amount of light for too long periods of time. \n\nPlants are tuned to natural light during ordinary hours but some plants can even "OD" on sunlight. When the sun shines too hot during a hot day they sometimes shutdown photosynthesis and begin to perspire. \n\nIt all comes down to what kind of plant it is. An ordinary house plant should release oxygen if the artificial light is not too intensive.

well photosynthesis is a good way to start. the water from the roots are pulled by cohesion and then it leaves from the stroma in the plant leaves.

The simple answer to your question is -- Yes, continuous exposure to an energetic enough light source and adequate supply of water and carbon dioxide WILL prohibit cellular respiration from taking place.  The reason for this is found in the processes that take place during both photosynthesis and cellular respiration.  \n\nFirst, photosynthesis takes place in two phases 1) photophosphorylation (which needs light to take place) and 2) carbon fixation (Calvin cycle – which can occur in the light or dark).  During photophosphorylation, energy in the form of light is captured and stored as NaDPH and/or ATP.  This is also the stage that utilizes the H+ proton from water molecules and releases oxygen as a by-product.  During the Calvin cycle, the carbon in carbon dioxide is “fixed” or assimilated into other products and some ATP is utilized to for the building blocks for the plant, such as glucose.  As I said before, as long at a photosynthetic plant has light, water, and CO2 (and other trace minerals of course), photosynthesis will continue.\n\nSo where does cellular respiration come it, and do plants even do it?  The answer is, yes, they do use cellular respiration and they do it when they need an alternate energy source when light is not present.  Keep in mind that cellular respiration is something akin to the opposite of photosynthesis and its purpose is to supply energy in the form of ATP by breaking down things like glucose.  This provides the needed maintenance energy at the expense of stored energy in the glucose.\n\nSo, why would constant exposure to light keep a plant from respiring?  The answer is – the plant has a constant source of ATP through the photophosphorylation phase of photosynthesis that there is no need to break down its stored “fuel” to provide maintenance energy.  In fact, if enough light is provided, the resulting photosynthesis will provide enough energy to meet maintenance needs and allow generation of building blocks and stored fuel.\n\nAs for the second part of your question, there are many reasons that a plant in natural light for only daylight hours might grow better than one continuously lit artificially.  Most likely though, this has to do with the availability of the necessary “ingredients” for growth mentioned above.  Especially of interest here is the INTENSITY of the light rather than the duration.  However, even if the intensity is high enough, if the other ingredients are lacking relative to the natural environment the plant will still suffer.\n\nHope that clarifies the issue for everyone.

Step 1 - ATP is invested by adding a P to glucose\n          Step 2 - Glucose-6-P is convertedinto Fructose-6-P\nStep 3 - A second ATP is invested \nStep 4 - The 6 carbon molecule issplit into two three carbon molecules.\nStep 4.5 - Dihydroxyacetone -P is converted into 3-P-glyceraldehyde\nStep 6 - every subsequent step occurs 2xNADH is produced as another P is added\nStep 7 - (2) ATP is recovered\nStep 8 - The P is moved from the 3-carbon to the 2-carbon\nStep 9 - A structural change is made\nStep 10 - (2) ATP is recovered\nStep 11 - NADH is produced anda CO2 is produced\n2 pyruvate are made from the process

Ultimately, photosynthesis is a reduction. One starts with carbon dioxide and reduces it through many steps to sugars and thence to cellulose and so on. The net result of all these steps is to reduce the number of carbon and oxygen bonds to a smaller number.

well theres alot of material i can provide you with but i dont know what particular experiment you are designing as there are always different experiments within an experiment.\nanyhow, i think this is an example of an experiment for photosynthesis and respiration and their pH levels.\n\nhttp://www.science.siu.edu/plant-biology/plb337/old_st_papers/emmert.pdf \n\n\nif you are doing the same experiment, i guess you will find this one really helpful.\n\n.. Good Luck

In Photosynthesis, plants use the sun's energy as light to transform carbon dioxide and water into glucose.  In cellular respiration,  glucose is ultimately broken down to yield carbon dioxide and water, and the energy from this process is stored as ATP molecules.

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.

B.\n\nCellular respiration uses Oxygen and releases CO2, and at Nighttime, Photosynthesis cannot occur(since there is a lack of light) and therefore cannot convert CO2 to O2, hence lowering the concentration

12H2O+ 6CO2 =C6H12O6+602 (chlorophyll & sunlight)-this is for photosynthesis\n\nC6H12O6 + 6O2 = 6CO2+6H2O + energy -this is for aerobic respiration where free molecular oxygen is required.\n\nphotosynthesis shows a constructive process so it is anabolism,on the other hand respiration is breakdown process,catabolism
