Chapter 23, Problem 23.43E

Interpretation Introduction

Interpretation:

The steps in the electron transport chain involving ATP synthesis are to be identified.

Concept introduction:

In electron transport chain, the hydrogen ions and the electrons carried by NADH and ${\text{FADH}}_{\text{2}}$ combine with oxygen to give water. This is a multistep process which involves several enzymes. It occurs in the inner membrane of mitochondria. The combined citric acid cycle, electron transport chain and oxidative phosphorylation are known as the catabolic pathway.
