Question

Cyclic photophosphorylation results in the formation of
(a) NADPH+ ${ H }^{ + }$
(b) ATP and NADPH+ ${ H }^{ + }$
(c) ADP
(d) ATP

Answer 1

It happens in aerobic and anaerobic conditions. Solely 2 sources of energy are available to live organisms: daylight and reduction-oxidation (redox) reactions. In a chemical change, this usually involves photolysis, or photodissociation, of water and a nonstop one-way flow of electrons from water to the photosystem II.

Complete answer
Cyclic photo-phosphorylation is the synthesis of ATP with an associate electron transport system that is activated by photosystem I. It happens within the stroma lamella. During this method, the system accomplishes the ADP to ATP for immediate energy for the cells.
Cyclic photophosphorylation occurs on the stroma lamellae or frets channels. In cyclic photophosphorylation, the high-energy electron released from P700 of PS1 flows down during a cyclic pathway. In cyclic electron flow, the electron starts in a color complex called photosystem I, passes from the essential acceptor to ferredoxin and afterward to plastoquinone, at that point to cytochrome ${ b }_{ 6 }{ f }$ (a comparable complex thereto found in mitochondria), at that point to plastocyanin prior to getting back to Photosystem-1. This transport chain creates a proton-thought process power, pumping ${ H }^{ + }$ particles over the film; this delivers a degree inclination that will be wont to control ATP synthase during chemiosmosis. This pathway is understood as cyclic photophosphorylation, and it produces neither ${ O }_{ 2 }$ nor NADPH. Unlike non-cyclic photophosphorylation, ${ NADP }^{ + }$ does not accept the electrons; they are instead sent back to the cytochrome ${ b }_{ 6 }{ f }$ complex.

So the correct answer is ‘ATP’

Note:
During the process of photosynthesis, the phosphorylation of ADP to shape ATP utilizing the energy of daylight is called photophosphorylation. Cyclic photophosphorylation happens in both aerobic and anaerobic conditions. Just two wellsprings of energy are accessible to living beings: daylight and reduction-oxidation (redox) responses. All living beings produce ATP, which is the widespread energy cash of life. In photosynthesis, this ordinarily includes photolysis, or photodissociation, of water and a nonstop unidirectional progression of electrons from water to photosystem II.
