What is an electron acceptor give examples?

What is an electron acceptor give examples?

An electron acceptor is an oxidizing agent and is itself reduced during the process of redox reaction. Examples of acceptors include oxygen, nitrate, iron (III), manganese (IV), sulfate, carbon dioxide, etc. See also: redox reaction, electron transport chain.

What is electron donor and acceptor?

Electron acceptors are ions or molecules that act as oxidizing agents in chemical reactions. Electron donors are ions or molecules that donate electrons and are reducing agents. Oxygen is an oxidizing agent (electron acceptor) and hydrogen is a reducing agent (electron donor).

Is the primary electron acceptor a protein?

Hence, the primary electron acceptor is probably an iron-sulphur protein. Using the same approach with spinach chloroplasts, a signal which is typical of a reduced iron-sulphur protein of plants is formed after a brief period of illumination.

What is the primary electron acceptor in landfills?

Carbon dioxide or acetic acid are the most commonly used electron acceptor in methanogenesis.

What is the primary electron acceptor in photosynthesis?

Excited P680 is a good electron donor and can transfer its excited electron to the primary electron acceptor, pheophytin. The electron will be passed on through the first leg of the photosynthetic electron transport chain in a series of redox, or electron transfer, reactions.

What is the first primary electron acceptor in the light reactions of photosynthesis?

Photosystem II Excited P680 is a good electron donor and can transfer its excited electron to the primary electron acceptor, pheophytin. The electron will be passed on through the first leg of the photosynthetic electron transport chain in a series of redox, or electron transfer, reactions.

What is the ultimate electron acceptor in the electron transport chain?

Oxygen
Oxygen is the terminal electron acceptor in the mitochondrial electron transport chain and therefore is required for the generation of energy through oxidative phosphorylation.

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.

What is the final electron acceptor in photosystem 2?

NADP+
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 primary acceptor in light reaction?

When the P680 special pair of photosystem II absorbs energy, it enters an excited (high-energy) state. Excited P680 is a good electron donor and can transfer its excited electron to the primary electron acceptor, pheophytin.
