Chapter 23, Problem 23.125EP

Interpretation Introduction

Interpretation: To write the full form of ROS.

Concept introduction: The human body inhale ${\text{O}}_{\text{2}}$ through respiration. $90\%$ of ${\text{O}}_{\text{2}}$ consumed is utilized by the electron transport chain and phosphorylation process. Some part of the remaining ${\text{O}}_{\text{2}}$ is converted into ROS.

ROS are important for the body but they have to be eliminated when they are not required as they are harmful when not needed.
