What is noncyclic electron flow?
In photosynthesis: The pathway of electrons. …and intermediate carriers is called noncyclic electron flow. Alternatively, electrons may be transferred only by light reaction I, in which case they are recycled from ferredoxin back to the intermediate carriers. This process is called cyclic electron flow.
Where does non cyclic electron flow occur?
Being a light reaction, non-cyclic photophosphorylation occurs in the thylakoid membrane.
What is the difference between noncyclic electron flow and cyclic electron flow?
1 Answer. Cyclic photo-phosphorylation in photosynthesis light dependent reaction leads to the formation of ATP and NADPH, and the electrons go from water to PSII to PSI and eventually to NADPH. In non-cyclic photo-phosphorylation only some ATP is produced and the electrons go from PSII to PSI and back again.
Is ps2 non cyclic?
(ii) PS II is involved in both cyclic and non-cyclic photophosphorylation.
What is non-cyclic?
Definition of noncyclic : not relating to or occurring in cycles : not cyclic a noncyclic process a noncyclical industry.
What is the difference between cyclic and noncyclic photosynthesis?
Non-cyclic photophosphorylation produces 1 ATP and 2 NADPH2 molecules….Difference Between Cyclic and Noncyclic Photophosphorylation.
| Cyclic Photophosphorylation | Non-Cyclic Photophosphorylation |
|---|---|
| Electrons tend to pass in a cyclic manner. | Electrons tend to pass in a non–cyclic manner. |
What is the importance of non-cyclic photophosphorylation?
The non- cyclic electron transport is most important in photosynthesis as it supplies assimilatory power in the form of NADPH and ATP for CO2 assimilation and purifies the atmospheric air. accept the electrons; they are instead sent back to cytochrome b6f complex.
What are the products of noncyclic electron flow?
Noncyclic photophosphorylation involves both Photosystem I and Photosystem II and produces ATP and NADPH.
Why is it called Z-scheme?
Why is it called Z-Scheme? It is simply because the diagram, when first drawn, was in the form of the letter “Z”.
Is Z-scheme non-cyclic photophosphorylation?
Z-scheme is the graphical representation of the electron transport pathway according to the redox potential pathway. It occurs in non-cyclic phosphorylation.
What is the main difference between cyclic and noncyclic photo?
Difference Between Cyclic and Noncyclic Photophosphorylation In cyclic photophosphorylation, P700 is known to be the active reaction center. In the non-cyclic photophosphorylation, P680 is known to be the active reaction center. Electrons tend to pass in a cyclic manner. Electrons tend to pass in a non–cyclic manner.
