Describe the flow of electrons in noncyclic photophosphorylation and compare it with that of cyclic photophosphorylation.

Explanation

Solution

The biochemical process which includes the addition of phosphate to an organic compound. Addition of phosphate to glucose results in glucose monophosphate and the addition of phosphate to adenosine diphosphate to form adenosine triphosphate are some examples.

Complete step by step answer:

Cyclic photophosphorylation Signifies to the synthesis of ATP during the light reaction of photosynthesis coupling to a cyclic passage of electrons to and from P700Noncyclicphotophosphorylation is the synthesis of ATP during the light reaction of photosynthesis in which an electron donor is required and oxygen is produced as a byproduct
Occurs in isolated chloroplasts and photosynthetic bacteriaOccurs in plants, algae, and cyanobacteria
electrons are separated from water and passed through PSII and PSI before ending up in NADPH. This process needs light to be absorbed twice once in each photosystem and it produces ATPOccurs in anoxygenic photosynthesisOccurs in oxygenic photosynthesis
Electrons move in a cyclic patternElectrons move in a linear pattern
Only photosystem I is involvedBoth photosystems I and II are involved
Electrons are at first expelled from the reaction center of PSIElectrons are first-expelled from the reaction center of PS II
Photolysis does not occurOxygen is not producedMainly occurs in anaerobic conditionsCannot be inhibited by DiuronPhotolysis occursOxygen is producedcoenzymes are producedMainly occurs in aerobic conditionsInhibited by Diuron

Note:
The other pathway non-cyclic photophosphorylation is known to be a two-stage process involving two different chlorophyll photosystems. Being a light reaction, non-cyclic photophosphorylation occurs in the thylakoid membrane of the granna's.
