Chapter 21, Problem 21.43AP

Interpretation Introduction

Interpretation:

It should be explained that why $ATP$ is defined as high energy molecule.

Concept Introduction:

Adenosine triphosphate ATP: The main job of $ATP$ is to store energy and release it when cell is in need of energy.  The $ATP$ produced as result of coupled reaction between electron transport chain and oxidative phosphorylation.

Coupled Reaction: It consists of reactions depend on each other in the way that energy released by one reaction drives other reaction.

Electron transport chain: The series of pathway where the electron gets passed from reduced coenzymes to the oxygen which gets finally coupled resulting in formation of $ATP$.

Oxidative phosphorylation: The production of $ATP$ from $ADP$ by utilizing energy released from the electron transport chain.  The $ADP$ to $ATP$ conversion consists of both the oxidation and phosphorylation.
