Concept explainers
Interpretation:
To identify the number of enzymes among the four enzyme complexes in the electron transport chain that function as proton pumps in oxidative phosphorylation.
Concept introduction:
Oxidative phosphorylation is the biochemical process for the synthesis of ATP from ADP and
When coenzymes (NADH and FADH2) gets oxidized, there is proton flow between the matrix and intermembrane space that is responsible for the buildup of
