What is the difference between non-cyclic and 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,
What is the difference between non-cyclic and 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 are the products of non-cyclic photophosphorylation?
Noncyclic photophosphorylation involves both Photosystem I and Photosystem II and produces ATP and NADPH.
What are the 3 products of Noncyclic photophosphorylation?
How are the products of noncyclic photophosphorylation produced: oxygen gas, ATP, NADPH? NADPH: The electrons get to the last protein, NADP Reductase, an enzyme whose substrate is NADP+. NADP Reductase adds the electrons to NADP+ to make NADPH.
What is the difference between cyclic and noncyclic photophosphorylation quizlet?
cyclic photophosphorylation exists to provide energy for the calvin cycle and involves only p680 in photosystem ll and its product is ATP. Non-cyclic photophosphorylation is carried out using p700 in photosystem l and p680 in photosystem ll and it produces nadph and atp.
What is the advantage of cyclic photophosphorylation?
The cyclic photophosphorylation also results in the formation of ATP molecules just like in non – cyclic photo phosphorylation. As the electrons move downhill in the electron transport chain, they lose potential energy and ATP molecules are formed in the same way as in mitochondria during respiration.
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.
Where does non-cyclic photophosphorylation occur?
granal thylakoid
Non-cyclic phosphorylation takes place in the granal thylakoid region of chloroplast. Two photosystems i.e. Photosystem-I and Photosystem-II is involved in the process of non-cyclic phosphorylation.
Is oxygen produced in non-cyclic photophosphorylation?
Non-cyclic photophosphorylation needs a constant supply of water molecules. The net result of non-cyclic phosphorylation is the formation of oxygen, NADPH and ATP molecules. Oxygen is produced as a waste product of photosynthesis.
Where does non-cyclic photophosphorylation takes place?
Complete answer: Non-cyclic phosphorylation takes place in the granal thylakoid region of chloroplast. Two photosystems i.e. Photosystem-I and Photosystem-II is involved in the process of non-cyclic phosphorylation.
Why does non cyclic photophosphorylation require water?
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 .
What is the advantage of cyclic flow of electrons?
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.
