Chapter 13, Problem 23P

Summary Introduction

To explain: The reason for no changes of ATP, but $\text{Pi}$ got changed within few minutes when a small amount of $\text{ATP}$ labeled with radioactive phosphorus at terminal position [γ-³²] ATP is added to yeast extract.

Introduction: Adenosine triphosphate is the cellular energy that involved in both catabolic and anabolic activities. Adenine is attached to ribose sugar. Ribose sugar is also connected to three phosphate groups. Phosphate group near the ribose sugar is termed as alpha phosphate group, next to it, is central phosphate group and last one is gamma phosphate group.
