Chapter 23, Problem 23.33E

Interpretation Introduction

Interpretation:

The primary function of the electron transport chain is to be stated.

Concept introduction:

Electron transport chain is the final stage in the oxidation of food. It leads to the formation of water molecule by the combination of hydrogen ions and electrons with molecular oxygen. The hydrogen ions and electrons are carried by the coenzymes ${\text{FADH}}_{\text{2}}$ and NADH. The coenzymes ${\text{FADH}}_{\text{2}}$ and NADH are the end products of the citric acid cycle.
