Is RuBP produced during cyclic electron flow in the light reactions of photosynthesis?
No, RuBP (ribulose-1,5-bisphosphate) is not produced during cyclic electron flow in the light reactions of photosynthesis. RuBP is a 5-carbon sugar molecule that plays a key role in the Calvin cycle, where it serves as the substrate for carbon fixation by Rubisco enzyme. Cyclic electron flow involves a cyclic pathway of electron transport to generate ATP without the release of oxygen or the production of NADPH.
What is cyclic and non cyclic?
Cyclic photophosphorylation is when the electron from the chlorophyll went through the electron transport chain and return back to the chlorophyll. Noncyclic photophosphorylation is when the electron from the chlorophyll doesn't return back but incorporated into NADPH.
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.
The cyclic pathway of ATP formation functions mainly to?
The cyclic pathway of ATP formation primarily functions to transfer electrons between electron carriers in order to generate a proton gradient across the inner mitochondrial membrane. This proton gradient is used by ATP synthase to produce ATP from ADP and inorganic phosphate.
Does cyclic electron flow in the chloroplast produce ATP glucose and NADPH?
9 ATP and 6 NADPH overall. This energy is supplied by the light reactions from photosystem II and photosystem I. 6 ATP are reduced to 6 ADP in stage 1( fixation). The 6 NADPH are reduced to form 6 NADP+ in stage 2(reduction). The final 3 ATP are used in stage 3(regeneration of acceptor).
Does non cyclic electron flow produce ATP?
No, non-cyclic electron flow does not directly produce ATP. It generates NADPH, which is used in the Calvin Cycle to produce ATP indirectly by providing reducing power for the synthesis of carbohydrates. ATP production occurs in cyclic electron flow by generating a proton gradient that drives ATP synthase.
What are the differences between cyclic and noncyclic electron flow?
in non-cyclic the electrons do not return the source and the cyclic the electrons come back to the source. Mostly the non-cyclic process occurs to produce ATP AND NADH which will be used by the Calvin cycle to produce the carbohydrate but some times there occurs a cyclic process to produce ATP to cope up with Calvin cycle as it requires more ATP than the NADH In addition to the above, cyclic electron flow could operate independent of photosystem II. The production of oxygen and NADPH take place in non-cyclic electron flow and the system could switch to cyclic flow upon accumulation of oxygen and NADPH
Is RuBP produced during cyclic electron flow in the light reactions of photosynthesis?

RuBP is a 5-carbon sugar molecule that plays a key role in the Calvin cycle, where it serves as the substrate for carbon fixation by Rubisco enzyme. Cyclic electron flow involves a cyclic pathway of electron transport to generate ATP without the release of oxygen or the production of NADPH.
Both cyclic and noncyclic electron flow generate the high-energy ATP molecule?
true
Electrons from what replace the electrons form photosystem 2 during non cyclic electron flow?
During non-cyclic electron flow, electrons come from water molecules that are split by photosystem II. These electrons replace the ones lost by photosystem II as they are passed along the electron transport chain.
Can Calvin cycle cyclic electron flow noncyclic electron flow or cellular respiration occur if the plant was placed in darkness for days?
as soon as the sun hits them they get all hiper and crazy.
When does non cyclic electron flow?
Non-cyclic electron flow occurs in the photosystems of plant chloroplasts during photosynthesis when electrons are transferred through both photosystem I and II to generate ATP and NADPH. This process does not involve the formation of ATP synthase or the production of ATP through chemiosmosis.
Where does cyclic electron transport occur?
Cyclic electron transport occurs in the thylakoid membrane of chloroplasts during the light reactions of photosynthesis. It involves the flow of electrons through the photosynthetic electron transport chain to generate ATP without the production of NADPH.
Why is neither oxygen or nadph generated by cyclic electron flow?
Cyclic electron flow occurs in photosystem I and involves the recycling of electrons within the photosystem, resulting in the production of ATP but not NADPH or oxygen. The electrons are cycled back to the electron transport chain to support ATP production, rather than being transferred to NADP+ to generate NADPH for the Calvin cycle.
What are the products of a non-cyclic electron flow?
The products of non-cyclic electron flow in photosynthesis are ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). This process occurs during the light-dependent reactions of photosynthesis and helps to generate energy-rich molecules that are used in the Calvin cycle to produce glucose.
What are electron carriers used in photosynthesis?
Pigment I & II systems of cyclic and non-cyclic phosphorylation.
Do both cyclic and non cyclic electrom flow generate the high energy ATP module?
true
