Chapter 20, Problem 29RE

Interpretation Introduction

Interpretation:

The difference in the spectroscopic properties among cytochromes is to be explained.

Concept introduction:

Cytochromes are the proteins that contain iron as their heme group.

$\text{NADH}-\text{CoQ}\text{oxidoreductase}$ is the first complex in the electron transport chain.

It catalyzes the transfer of electrons from $\text{NADH}$ to $\text{coenzyme}\text{Q}$.

$\text{succinate}-\text{CoQ}\text{oxidoreductase}$ is the second complex of the electron transport chain.

$\text{coenzyme}\text{Q}$ is the redox coenzyme in the mitochondrial electron transport.
