How does cyclic photophosphorylation differ from noncyclic Photophosphorylation?
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 difference between cyclic and noncyclic process?
A cyclic process consists of a series of changes which return the system back to its initial state. In non-cyclic process the series of changes involved do not return the system back to its initial state.
How does cyclic photophosphorylation differ from linear photophosphorylation?
Photophosphorylation is defined as the addition of phosphate group during the light reaction of photosynthesis in the presence of light.

What is produced in Noncyclic photophosphorylation and not in cyclic phosphorylation?
Electrons from Photosystem I are accepted by NADP. ATP molecules are produced. Both NADPH and ATP molecules are produced. Water is not required.

Why do both the cyclic and the Noncyclic photophosphorylation exist?
Both cyclic and non cyclic linear electron transport occur in higher plants chloroplast to maintain the required metabolic rate resulted in production of ATP and NADPH. The cyclic produces only ATP and no reducing powers.
What is the difference between cyclic and noncyclic electron flow and why would a plant need both?
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.
Does cyclic and non cyclic photophosphorylation occur at the same time?
The chloroplast will continue cyclic photophosphorylation until the ATP supply has been replenished. ATP is produced through chemiosmosis in both cyclic and non-cyclic photophosphorylation.
What does non cyclic photosynthesis achieve that Cannot be provided by a cyclic Photosynthesizer?
What does non-cyclic photosynthesis achieve that cannot be provided by a cyclic photosynthesizer? A source of reducing power for biosynthesis. During aerobic respiration, electrons are taken from NADH (H+) transported by a multistep pathway and then used to reduce O2 to H2O.
What happens in non-cyclic photophosphorylation?
In a process called non-cyclic photophosphorylation (the “standard” form of the light-dependent reactions), electrons are removed from water and passed through PSII and PSI before ending up in NADPH. This process requires light to be absorbed twice, once in each photosystem, and it makes ATP .
Why would an organism perform cyclic phosphorylation instead of Noncyclic phosphorylation?
Noncyclic photophosphorylation is used in oxygenic photosynthesis when there is a need for both ATP and NADPH production. If a cell’s needs for ATP outweigh its needs for NADPH, then it may carry out cyclic photophosphorylation instead, producing only ATP.
What is the purpose of cyclic phosphorylation?
Cyclic Photophosphorylation is the process in which organisms (like prokaryotes), just accomplish the conversion of ADP to ATP for immediate energy for the cells. This type of photophosphorylation usually occurs in the thylakoid membrane.
What is the importance of photosynthesis to cyclic flow of material?
In higher plants, the generation of proton gradient across the thylakoid membrane (ΔpH) through cyclic electron flow (CEF) has mainly two functions: (1) to generate ATP and balance the ATP/NADPH energy budget, and (2) to protect photosystems I and II against photoinhibition.
Which of the following does not occur in cyclic electron transport and phosphorylation?
Cyclic photophosphorylation produces ATP only. It does not involve the formation of NADPH.
What is the advantage of cyclic photophosphorylation?
Advantages of Cyclic Photophosphorylation
It allows for different pigments to absorb huge bands of light. Non-cyclic Photophosphorylation is easier for the plant since it uses only one photosystem. Non-cyclic Photophosphorylation produces ATP and NADPH; cyclic produces the only ATP.
What advantage does cyclic photophosphorylation hold over Noncyclic photophosphorylation?
Noncyclic photophosphorylation is easier for the plant since it uses only one photosystem. C. Noncyclic photophosphorylation produces ATP and NADPH; cyclic produces only ATP.
What are the similarities between cyclic and non cyclic electron transport?
Similarities Between Cyclic and Noncyclic Photophosphorylation. Both cyclic and noncyclic photophosphorylation occur during the light reaction of photosynthesis. Cyclic and noncyclic photophosphorylation are two types of ETS. Both cyclic and noncyclic photophosphorylation are light-dependent.
