What are the electron donors and acceptors for cyclic photophosphorylation?

What are the electron donors and acceptors for cyclic photophosphorylation?

The electron flow is between PSII, Cytochrome b6f, and PSI. The electron in PSI receives energy from other photons. NADP is the ultimate electron acceptor. Water is the first electron donor in oxygenic photosynthetic reactions.

What is the final electron acceptor in non cyclic photophosphorylation?

The final electron acceptor is NADP. In cyclic photophosphorylation, cytochrome b6f uses the energy of electrons from not only PSII but also PSI to create more ATP and to stop the production of NADPH.

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.

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.

What is the final electron acceptor during oxidative phosphorylation?

oxygen
Given its greater availability in the atmosphere, elemental oxygen is used as the final electron acceptor in oxidative phosphorylation.

Which of the following is the final electron acceptor in photosynthesis?

NADP
The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. In anoxygenic photosynthesis various electron donors are used.

What is the final electron acceptor in photosystem 2?

The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product.

What is the final acceptor of electrons during the noncyclic electron pathway?

The final acceptor of electrons during the noncyclic electron pathway is what? NADP+. You just studied 19 terms!

What is the final electron acceptor in Calvin cycle?

NADPH is the reduced form of the electron acceptor NADP+. At the end of the light reactions, the energy from sunlight is transferred to NADP+, producing NADPH. This energy in NADPH is then used in the Calvin cycle.

Is NADP the final electron acceptor?

The final electron acceptor is NADP. In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product. Cyclic phosphorylation is important to create ATP and maintain NADPH in the right proportion for the light-independent reactions.

What happens to electrons 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.

Where does cyclic photophosphorylation occur in the thylakoid membrane?

This process usually takes place in the thylakoid membrane and uses Photosystem I and the chlorophyll P700. During cyclic photophosphorylation, the electrons are transferred back to P700 instead of moving into the NADP from the electron acceptor. This downward movement of electrons from an acceptor to P700 results in the formation of ATP molecules.

How is ATP produced in the photophosphorylation process?

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.

Which is the active reaction center in cyclic photophosphorylation?

In Cyclic PhotophosphorylationP700 is the active reaction center. In non-Cyclic PhotophosphorylationP680 is the active reaction center. Electrons passes in a cyclic manner.
