Is RuBP produced during cyclic electron flow in the light reactions of photosynthesis?
No , it is regenerated in Calvin cycle .
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 purpose of electron carriers in cellular respiration?
The purpose of electron carriers such as NADH and FADH2 is to dump electrons at the electron transport chain. This creates a proton gradient and allows oxidative phosphorylation to take place.
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.
Is the scientific method cyclic or linear?
is the scientific method cylic or linear?
Does non cyclic electron flow produce ATP?
yes
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
Both cyclic and noncyclic electron flow generate the high-energy ATP molecule?
true
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.
Why is neither oxygen or nadph generated by cyclic electron flow?
During oxygenic photosynthesis, photosystem (PS) 1 and 2 cooperate to achieve a linear electron flow from H20 to NAPD.
Is RuBP produced during cyclic electron flow in the light reactions of photosynthesis?
No , it is regenerated in Calvin cycle .
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 are the products of a non-cyclic electron flow?
In photosynthesis, the noncyclic electron flow produces enzymes called cytochrome b6f complex. Its function is to catalyze the electron transfer of plastoquinol to plastocyanin.
What are electron carriers used in photosynthesis?
Pigment I & II systems of cyclic and non-cyclic phosphorylation.
Where do extra ATP molecules come from in the Calvin Cycle?
ATPand NADP are formed during light reaction.i.e.,during cyclic photophosphorylation.
Do both cyclic and non cyclic electrom flow generate the high energy ATP module?
true
Which pathways in photosynthesis will produce ATP but not NADPH?
non-cyclic electron pathways
