Chapter 4.2, Problem 3MC

Summary Introduction

To determine:

The protein that is oxidized and that is reduced when electrons pass from the first to the second protein in the electron transport chain.

Introduction:

Electrons can carry energy. The energy transformations in organisms mostly occur in oxidation-reduction (redox) reactions. These reactions transfer energized electrons from one molecule to another electron. Oxidation means the loss of electrons, and their energy from a molecule, an atom, or an ion. Reduction means a gain of electrons and their energy.
