Which compound is formed in the process of photosynthesis?

Participants in Photosynthesis
Chloroplasts are organelles specialized for photosynthesis. Inside chloroplasts are chlorophyll, proteins which can absorb light. Photosystems are many proteins together which can gather and amplify light energy. NADPH is an energy carrier in plants and ATP synthase produces the ATP.

In respiration energy is released fromsugars when electrons associated with hydrogen are transported to oxygen (theelectron acceptor), and water is formed as a byproduct. The mitochondriause the energy released in this oxidation in order to synthesize ATP. Inphotosynthesis, the electron flow is reversed, the water is split (not formed),and the electrons are transferred from the water to CO2 and in theprocess the energy is used to reduce the CO2 into sugar. Inrespiration the energy yield is 686 kcal per mole of glucose oxidized to CO2,while photosynthesis requires 686 kcal of energy to boost the electrons from thewater to their high-energy perches in the reduced sugar -- light provides thisenergy.

Rather it is produced by one setof reactions and is almost immediately consumed by another.

Can be produced by photosynthesis

Adenylate kinaserequires an atom of magnesium—and this is one of the reasonswhy sufficient dietary magnesium is important.

What is photosynthesis and why it is important
Photosynthesis is a process during which energy from light is harvested and used to drive synthesis of organic carbohydrates from carbon dioxide and water, generating oxygen. Photosynthesis is the only way that radiant energy from the sun can be converted into organic molecules for plants and animals to consume.

Light reaction and photophosphorylation
Pigments embedded on thylakoid membranes form photosystems. There are of two types: PS I P700, PS II P680. Components of photosystem I and II transfer the electrons from water to NADP via cyclic electron transfer or non-cyclic electron transfer. During electron transfer, the light energy captured by the photosynthetic organisms is transformed into the phosphate bond energy of ATP. This is called photophosphorylation. NADPH is generated during non-cyclic electron transfer.

During what stage of photosynthesis are ATP and ..

During photosynthesis, molecules of oxygen are liberated from the "splitting" of water molecules due to the (a) dark reactions (b) light reactions (c) formation of PGAL (d) formation Of C02





Once againplausible transitional forms have never been found that can linkthis form of ATP production to the chloroplast photosynthesis system.

Photorespiration
Under high oxygen and low carbon dioxide conditions, Rubisco favors binding to oxygen instead of carbon dioxide, therefore the energy produced in light reactions are consumed for no productivity of organic carbohydrates. The final result is that oxygen is consumed and CO2 is produced, which mimics respiration, and therefore named photorespiration.

How is ATP used in photosynthesis? - Quora

Dark reaction – Calvin cycle
Second step of photosynthesis is called Calvin’s cycle. Because it does not require light, so it is called dark reaction. During dark reaction, the ATP and NADPH generated by light reaction are consumed to fix carbon dioxide into organic carbohydrates. The first fixed carbohydrate is a three carbon compound 3-phosphoglycerate (3PGA). The final product is a high-energy 3 carbon compound glyceraldehyde-3-phosphate (G3P) which can be used to synthesize a broad range of organic molecules. An important intermediate molecule for carbon dioxide fixation is ribulose bisphosphate (RuBP), and the enzyme catalyzing the CO2 fixation is Rubisco.

What energy-rich organic compound is produced …

Photosynthesis is a process where by energy from light is harvested and used to drive synthesis of organic carbohydrates from carbon dioxide and water. Photosynthesis takes place in chloroplasts and can be divided into two steps: light reactions which require light and dark reactions which do not require light. During light reaction, light energy is captured by photosystems and electrons are transferred among the electron receptors. ATP and NADPH are generated. During dark reactions, CO2 is fixed using ATP and NADPH generated by the light reactions and organic carbohydrates are synthesized via the Calvin Cycle. When the CO2 is first fixed into a 3 carbon compound 3PGA, it is called C3 pathways and these plants are called C3 plants. The disadvantage of C3 plants is that they undergo photorespiration and thus waste some energy gained in light reactions. C4 cycle is the pathway adopted by C4 plants to bypass photorespiration.
