What is the fate of the NADPH molecules created during noncyclic photophosphorylation?
NADPH molecules created during noncyclic photophosphorylation are used in the Calvin cycle to help convert carbon dioxide into glucose, a process known as carbon fixation. The NADPH molecules provide reducing power necessary for the synthesis of sugars in the stroma of the chloroplast.
What is the difference between cycle and noncycle photophosphorylation?
Cycle photophosphorylation occurs in cyclic electron flow, where electrons are recycled to produce ATP but not NADPH. Noncyclic photophosphorylation involves both photosystems I and II to produce both ATP and NADPH using electrons extracted from water.
Is carbon dioxide is reduced during the Calvin cycle in photosynthesis?
yes, it is. <- Trolololol. CO2 is first fixated by adding CO2 to Organic Compounds (external or Auto made) to make it RuBP. The Reduction part is the Use of ATP and NADPH from noncyclic part of photophosphorylation, to energize CO2-> carbohydrate.
What is returned to chlorophyll in cyclic photophosphorylation that is not returned in noncyclic photoreduction?
In cyclic photophosphorylation, electrons are returned to the reaction center of the chlorophyll molecule, allowing for the production of ATP. In noncyclic photoreduction, electrons are not returned to the same chlorophyll molecule but are instead transferred to other molecules, like NADPH, for use in the Calvin cycle.
What does non-cyclic photophosphorylation produce?
Non-cyclic photophosphorylation, which occurs in the light-dependent reactions of photosynthesis, produces ATP and NADPH. These molecules serve as energy carriers that are used in the Calvin cycle to produce sugars.
What is the two products of photophosphorylation that drives the Calvin cycle?
The two products of photophosphorylation that drive the Calvin cycle are ATP and NADPH. ATP provides the necessary energy for the conversion of carbon dioxide into glucose, while NADPH supplies the reducing power needed for the reduction of 3-phosphoglycerate to glyceraldehyde-3-phosphate. Together, these molecules are essential for synthesizing carbohydrates during the Calvin cycle.
What cycle are produced in the chloroplast?
During The Calvin Cycle cycle, sugars are produced in the chloroplast.
Which is the product in the Calvin cycle?
Glucose is a product of the Calvin cycle. However, other sugars can be produced in the cycle, and ADP and NADP+ are also produced from the formation of glucose.
When does carbohydrate production occur in a chloroplast?
During The Calvin Cycle cycle, sugars are produced in the chloroplast.
In the Calvin cycle ATP are used to make glucose What is the source of the ATP?
In the Calvin cycle, ATP is produced during the light-dependent reactions of photosynthesis. These reactions occur in the thylakoid membranes of chloroplasts, where sunlight is captured by chlorophyll and used to generate ATP and NADPH through processes like photophosphorylation. The ATP and NADPH generated then provide the energy and reducing power needed for the Calvin cycle to convert carbon dioxide into glucose.
What is the fate of electrons in noncyclic photophosphorylation?
The electrons released by P700 of PS-I in the presence of light are taken up by the primary acceptor and are then passed on to ferredoxin (Fd), plastoquinone (PQ), cytochrome complex, plastocyanin (PC) and finally back to P700 i.e., electrons come back to the same molecule after cyclic movement.
Are nadph and ATP produced by the Calvin cycle?
Yes, they carry energy between the light reactions and the Calvin cycle. ADP is phosphorylated into ATP at the ATP synthase while NADP is reduced by the electrons in the transport chain (it then becomes NADPH).
