What is netgain light reaction?
The net gain of light reaction in non cyclic photophosphorylation is 3 ATP and 2 NADPH and oxygen is evolved. While in cyclic photophosphorylation 1 ATP is gained.
You measure the amount of ATP and nadph consumed by the Calvin cycle in 1 hour you find 30000 molecules of ATP consumed but only 20000 molecules of nadph where did the extra ATP molecules come fro?
cyclic photophosphorylation
Where do extra ATP molecules come from in the Calvin Cycle?
ATPand NADP are formed during light reaction.i.e.,during cyclic photophosphorylation.
What does non-cyclic mean?
cyclic phosphorylationinvolve PS1 onlyonly ATP producedno photolysis of waterfinal acceptor not NADP,so no production NADPHnon-cyclic phosphorylationinvolve PSI and PSIIATP and NADPH producedinvolved photolysis of waterfinal acceptor is NADP,so there is production NADPH
The cyclic pathways of photosynthesis produce?
O2, ATP and NADPH ONLY ATP IS PRODUCED. NEITHER O2 NOR NADPH IS PRODUCED.
A product of cyclic photophosphorylation is?
ATP only
What is netgain light reaction?
The net gain of light reaction in non cyclic photophosphorylation is 3 ATP and 2 NADPH and oxygen is evolved. While in cyclic photophosphorylation 1 ATP is gained.
What does non-cyclic photophosphorylation produce?
It produced ATP, O2, and NADPH.
What is photophosphoryylation?
Photophosphorylation is the production of ATP using the energy of sunlight.
In noncyclic photophosphorylation what is the ultimate acceptor of electrons that have been produced from the splitting of water?
Carbon dioxide is a noncyclic photophosphorylation and is the ultimate acceptor of electrons that have been produced from the splitting of water. A product of both cyclic and noncyclic photophosphorylation is ATP.
What is the end product of noncyclic photophosphorylation?
Cyclic photophosphorylation is the production of some ATP in the light dependent stage of photosynthesis. No photoylsis of water occurs and therefore no reduced NADP is produced either. Only photosystem one is involved here and as light is absorbed by the photosystem, two electrons are released which are accepted by the electron transfer chain. As the electrons are transferred along the chain, energy is released which pumps protons across the thylakoid membrane. A proton gradient forms and the protons diffuse through protein channels associated with ATP synthase enzymes, the proton motive force along with the enzyme combine ADP and inorganic phosphate atom to create ATP. The flow of protons which creates the ATP is chemiosmosis. The ATP can then be used in the light independent stage of photosynthesis or to actively transport potassium ions into the guard cells, so they become turgid as a result of water entering by osmosis. This causes the stomata to open and carbon dioxide can readily diffuse in - increasing the rate of photosynthesis.

What is the chemiosmosis production of ATP compared to in photosynthesis?
The chemiosmotic production of ATP through photophosphorylation in photosynthesis is closely related to the chemiosmotic production of ATP through oxidative phosphorylation in cellular respiration. Both processes utilize a proton gradient across a membrane to power the ATP synthase which phosphorylates ADP into ATP.
What are the products of photophosphorylation?
ATP and NADPH
What is the production of ATP in photosynthesis called?
Glycolysis produces ATP in plants to power cellular processes. Photosynthesis harnesses the energy from the sun and stores it in glucose molecules.
What is photophosphorylation?
Photophosphorylation refers to the use of light energy from photosynthesis. Ti provides the energy to convert ADP to ATP.
