Chapter 10, Problem 41FB

Summary Introduction

To review:

The blank space in the statement “Under conditions of _____, the antioxidant mechanisms of cells are overwhelmed.”

Introduction:

The use of oxygen as the final electron acceptor in the electron transport chain carries a significant risk of its own. This risk is the formation of superoxide radicals or reactive oxygen species (ROS) that can damage the body in a number of ways, if not properly contained. Usually, antioxidants serve to mitigate most of the damage, but on occasion, can be overwhelmed.
