Which of the following processes generates a proton-motive force in mitochondria?
Sauron [17]

Answer:

The correct answer is option d.

Explanation:

At the time of the electron transport chain, the transferring of electrons takes place from the level of higher energy to the level of lower energy at each of the steps that result in the discharging of energy. This energy discharged is utilized to pump the proton found in the matrix into the intermembrane space across the inner mitochondrial membrane.  

This process of proton pumping from the mitochondrial matrix to the intermembrane space results in a proton gradient, which is, utilized in the generation of ATP.
