What is the primary electron acceptor in cyclic photophosphorylation?

-Cyclic photophosphorylation is operated at a very high rate in the bundle sheath chloroplast of certain C4 plants. -The electron released by P700 in the presence of light is passed as the primary acceptor, ferredoxin, plastoquinone, cytochrome complex, plastocyanin, and finally back to P700.

Which is the last electron acceptor in Noncyclic photophosphorylation?

NADP+
Therefore the electron acceptor in non-cyclic photophosphorylation is NADP+.

Is oxygen the final electron acceptor in photophosphorylation?

Explanation: Oxygen is the final electron acceptor in the electron transport chain, which allows for oxidative phosphorylation. Without oxygen, the electrons will be backed up, eventually causing the electron transport chain to halt.

Where is the final electron acceptor in photosynthesis?

NADPH is produced from NADP+. It appears in the last step of the electron chain of the light reactions of photosynthesis . In the light reactions, NADP+ is the last electron acceptor which then accepts a proton to become NADPH which is a reducing agent.

What is the final electron acceptor in photosystem 2?

The light reactions of photosynthesis, which take place in photosystems II and I. Light energy is harvested and used to power the transfer of electrons among a series of electron donors and acceptors. The final electron acceptor is NADP+, which is reduced to NADPH.

What is the primary electron acceptor in photosystem 2?

Kinetics and mechanism of electron transfer in intact photosystem II and in the isolated reaction center: Pheophytin is the primary electron acceptor.

Which one acts as final electron acceptor in ETS of chloroplast?

Since oxygen is the final electron acceptor, the process is called aerobic respiration.

What is the final electron acceptor is?

Oxygen is the final electron acceptor in this respiratory cascade, and its reduction to water is used as a vehicle by which to clear the mitochondrial chain of low-energy, spent electrons.

Which of the following is the final electron acceptor in the light reaction?

NADPH
The final electron acceptor in the light reactions is NADPH.

What is the primary electron acceptor in Photosystem 1?

Ferredoxin
The first electron acceptor in the case of photosystem I is A0 which is modified chlorophyll. After which it gets transferred to phylloquinone, phylloquinone then transfers it to Ferredoxin.

What happens to electrons released during non-cyclic 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 energy is used in photophosphorylation?

In photophosphorylation process, light energy is used to make a high-energy electron donor and a lower-energy electron acceptor. Electrons then move suddenly from donor to acceptor through an electron transport chain. ATP is produced by an enzyme called ATP synthase.

What is cyclic electron flow in photosynthesis?

In cyclic electron flow, the electron starts in a pigment complex called photosystem I, then it passes from the primary acceptor to ferredoxin then to plastoquinone, and then to cytochrome b6f (a similar complex to that is also found in mitochondria), and then to plastocyanin before coming back to chlorophyll.

How do electrons travel in a non-cyclic way?

Electrons travel in a non – cyclic manner. Electrons from Photosystem I are accepted by NADP. ATP molecules are produced. Both NADPH and ATP molecules are produced. Water is not required. Photolysis of water is present. NADPH is not synthesized. NADPH is synthesized. Oxygen is evolved as a by-product. This process is predominant only in bacteria.
