What is the differences between cyclic and non-cyclic photophosphorylation?

What is the differences between cyclic and non-cyclic photophosphorylation?

In the cyclic photophosphorylation, only ATP is produced, whereas, in the non-cyclic photophosphorylation both NADPH and ATP are produced. On the other hand, in non-cyclic photophosphorylation, the electrons that are expelled by the photosystems do not return.

What is cyclic photophosphorylation and Noncyclic photophosphorylation?

Photophosphorylation happens on the stroma lamella or frets. In cyclic photophosphorylation, the high energy electron is free from P700 to ps1 flow down to a cyclic pathway. On the other hand, non-cyclic photophosphorylation, NADP+ does not take the electrons; they instead sent back to cytochrome b6f complex.

Which of the following is common between cyclic and noncyclic electron transport?

Cyclic photophosphorylation	Non-cyclic photophosphorylation
2- Only Atp is produced	2- Both ATP and NADPH are produced.
3- Electrons expelled by photosystem and return back.	3- Electrons expelled by photosystem but do not return back.
4- Photolysis of water does not occur.	4- Photolysis of water occur.

Why is non-cyclic photophosphorylation important?

This process of ATP production is called non-cyclic photophosphorylation. The ATP generated in this process will provide the energy for the synthesis of glucose during the Calvin cycle (light independent reactions). NADPH is the reducing agent needed for the synthesis of glucose in the Calvin cycle.

What is not observed during cyclic photophosphorylation?

Non-cyclic photophosphorylation involves both PS-1 and PS-11. Here electrons are not cycled back and are used in the reduction of NADP to NADPH,. It involves production of two ATP molecules, no NADPH, is produced.

What do you mean by non-cyclic photophosphorylation?

non-cyclic photophosphorylation The light-requiring part of photosynthesis in higher plants, in which an electron donor is required, and oxygen is produced as a waste product. It consists of two photoreactions, resulting in the synthesis of ATP and NADPH 2.

What is the difference between non cyclic and cyclic photophosphorylation?

Non-Cyclic Photophosphorylation. The photophosphorylation process which results in the movement of the electrons in a non-cyclic manner for synthesizing ATP molecules using the energy from excited electrons provided by photosystem II is called as non-cyclic photophosphorylation.

What happens to P700 during noncyclic photophosphorylation?

During non-cyclic photophosphorylation, the electrons released by P700 are carried by primary acceptor and are finally passed on to NADP. Here, the electrons combine with the protons – H+ which is produced by splitting up of the water molecule and reduces NADP to NADPH2. Also Read: Photosynthesis.

What kind of phosphorylation occurs in presence of light?

Since this phosphorylation is occurring in presence of light, it is called photophosphorylation. Depending upon the path of electrons in the electron-transport-system of the primary photochemical reaction, there are two types of photophosphorylation processes. They are (1) Cyclic photophosphorylation and (2) Noncyclic photophosphorylation.

How is NADP used in non-cyclic photophosphorylation?

In noncyclic photophosphorylation. The transport of electrons is in a non-cyclic manner, these electrons from the photosystem1 (P700) are accepted by NADP. In non-cyclic photophosphorylation ATP and NADP both are produced that are utilized as an energy source, (NADP is a rich energy source as 1 NADP give energy equivalent to 3 ATPs).
