Is NADP an electron acceptor?
The final electron acceptor is NADP.
In oxygenic photosynthesis, the first electron donor is water, creating oxygen as a waste product.
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..
Is NADH an electron acceptor?
Like the food molecule, NADH functions as an electron donor. The electron transporters embedded in the mitochondrial membrane are oxidoreductases that shuttle electrons from NADH to molecular oxygen, another electron acceptor. … NADH undergoes a reverse reaction, converting back to NAD+.
Is hydrogen an electron acceptor?
Electron acceptors are ions or molecules that act as oxidizing agents in chemical reactions. Oxygen is an oxidizing agent (electron acceptor) and hydrogen is a reducing agent (electron donor). …
What is the final electron acceptor for hydrogen?
OxygenOxygen is the final hydrogen ion and electron acceptor. The oxygen combines with the hydrogen ions and electrons to form water. In total, 38 ATP molecules are produced from one molecule of glucose.
What is the electron acceptor in cellular respiration?
oxygenExplanation: In cellular respiration, oxygen is the final electron acceptor. Oxygen accepts the electrons after they have passed through the electron transport chain and ATPase, the enzyme responsible for creating high-energy ATP molecules.
Is hydrogen sulfide a good electron acceptor?
Many denitrifying bacteria can also use ferric iron (Fe3+) and different organic electron acceptors. Sulfate reduction uses sulfate (SO2−4) as the electron acceptor, producing hydrogen sulfide (H2S) as a metabolic end product.
