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!!

Adenosine Triphosphate, or ATP as it is commonly known, is the cells currency for providing energy. ATP is made in the mitochondria via respiration (more precisely oxidative phosphorylation). This process involves the addition of a phosphate group to a pre-existing adenosine diphosphate group. The ATP is then transported out of the mitochondria and transported around the cell to where reactions occur that require energy input.At these sites ATP is hydrolysed (water added) to form ADP (ATP +  H20 = ADP + P + Energy). The energy is provided in the form of heat energy which is usually used in catabolic reactions to break bonds.

What's your question about it?\n\nThis is the mechanism by which ATP is produced in bacteria, mitochondria and chlorplasts.  Energy for the formation of ATP (by the enzyme ATP synthase) is provided by a proton charge and concentration gradient across a membrane (inner mitochondrial membrane or thylakoid membrane, or plasma membrane in bacteria).  What else would you like to know?

in the first stage (the light dependent stage) water is broken down (releasing oxygen) to donate electrons to antenae pigments, which "absorb" light and use it's energy to make ATP and NADPH\n\nin the second light independent stage, ATP and NADPH made from the first stage are combined with CO2 in the calvin cycle to make G3P, which can make Glucose or materials to keep the calvin cycle going.

Photosynthesis (photo=light, synthesis=putting together), generally, is the synthesis of sugar from light, carbon dioxide and water, with oxygen as a waste product. It is arguably the most important biochemical pathway known; nearly all life depends on it. It is an extremely complex process, comprised of many coordinated biochemical reactions. It occurs in higher plants, algae, some bacteria, and some protists, organisms collectively referred to as photoautotrophs.\n\nPhotosynthesis uses the energy of light to make the sugar, glucose. A simple general equation for photosynthesis follows.\n\n6 CO2 + 12 H2O + light → C6H12O6 + 6 O2 + 6 H2O\ncarbon dioxide + water + light energy → glucose + oxygen + water\nPhotosynthesis occurs in two stages. In the first phase light-dependent reactions or photosynthetic reactions (also called the Light reactions) capture the energy of light and use it to make high-energy molecules. During the second phase, the light-independent reactions (also called the Calvin-Benson Cycle, and formerly known as the Dark Reactions) use the high-energy molecules to capture carbon dioxide (CO2) and make the precursors of glucose.

Photosystems I and II in plant cells both absorb light energy from the sun to perform photosynthesis. Neither system absorbs green wavelength of light, which is why plant leaves look green.\nPhotosystem I absorbs 700 nanometer wavelengths the best while Photosystem II absorbs 680nm wavelengths the best.\n\nIn Photosynthesis, Photosystem II comes before photosystem I. (the numbering is mixed up because P1 was discovered before P2). First, in P2, water is split by light energy and the electrons released by the reaction travel to an electron acceptor which produce ATP. P1 does the same thing as P2 but in addition, its electron acceptor also receives the electrons used by P2.\n\nThese two photosystems make up the light reaction part of photosynthesis. The energy (ATP) made in this reaction drives the dark reaction part of photosynthesis, where carbon dioxide is converted to glucose sugar.

Chloroplasts contain structures called thylakoids.\n\nThe thylakoid membrane contains the two photosystems utilized by photosynthesis. Most simply, when light strikes the reaction centers of the photosystems, electrons are released into an electron transport chain. As electrons move through the chain,  protons are pumped from the stroma of the chloroplast to the lumen (inside) of the thylakoid. Since the thylakoid membrane is impermeable to protons, a gradient is eventually built up within the thylakoid. This gradient powers ATP synthesis.

ATP is formed by adding a phosphate group to ADP along with some energy. The process by which ATP is generated from ADP is called phosphorylation.  There are three types of phosphorylations: substrate-level, oxidative phosphorylation, and photophosporylation. \n\nEnergy stored in ATP is used in nearly all of the endergonic reactions in cells. ATP is often reffered to as the energy currency of the cell.

Don't quote me on this one, but the energy produced via redox reactions when electrons are passed down the electron transport chain, is used to pump protons against their concentration gradient.\nIn the mitochondria, the protons are pumped into the space between the inner and outer membranes, whereas in chloroplasts, the protons are pumped into the space in the thylakoid. The accumulation of protons in those spaces causes the pH to drop, and sets up a voltage and a concentration gradient, thus causing protons to diffuse through proton channels in the enzyme ATP synthetase. This causes a part of ATP synthetase to rotate, and the energy produced is use to phosphorylate ADP to ATP.\nIn the mitochondria, the electrons are combined with a proton and oxygen at the end of the chain, so water is produced as a waste product.\nIn chloroplasts, the electron transport chain is located between Photosystems II and I, thus an electron from Photosystem II is passed onto Photosystem I. Photosystem I, having been excited and ionised beforehand, therefore returns to being electrically neutral.

Photosynthesis is the process by which plants convert carbon dioxide and water to glucose for energy. It takes place in the cholorplasts of the cell, which contain chlorophyll. There are two parts to photosynthesis, the light reactions, and the dark reactions, or the Calvin cycle. In the light reactions, light energy triggers electrons to form ATP and NADPH from ADP and NADP through the electron transport chain. This part also takes water and releases oxygen.\n\nIn the calvin cycle, RuBP uses carbon dioxide to create glucose, which is the energy the plant needs to function. \n\nThe products released from photosynthesis are water and oxygen.
