Question

Denitrification is the process where

Question 4 options:

Nitrogen gas is reduced to nitrate, generating a proton mobive force.

nitrate generates ATP via substrate level phosphorylation.

Nitrogen gas generates ATP via substrate level phosphorylation.

nitrate or nitrite are used as electron acceptors to generate a proton motive force.

A)

Nitrogen gas is reduced to nitrate, generating a proton mobive force.

B)

nitrate generates ATP via substrate level phosphorylation.

C)

Nitrogen gas generates ATP via substrate level phosphorylation.

D)

nitrate or nitrite are used as electron acceptors to generate a proton motive force.

Explanation / Answer

nitrate or nitrite are used as electron acceptors to generate a proton motive force.

Nitrate or nitrite act as NOx reductases and accept electrons in the canonical respiratory chain of denitrificaton. Protons are removed and this acceptance of electrons results in the generation of proton motive force.
