Chapter 13, Problem 22P

(a)

Summary Introduction

To determine: The free energy required to synthesize $\text{ATP}$ in the human hepatocyte when the physiological concentrations of $\text{ATP}$,$\text{ADP}$ and $\text{Pi}$ are $3.5$,$1.50$, and $5.0$$\text{mM}$, respectively.

Introduction:

The adenosine triphosphate (ATP) is a complex organic compound which is produced during the process of cellular respiration. Cellular respiration is the process by which energy is produced in a cell. Energy is released from the breakdown of glucose in cellular respiration that is used by the cell for performing various life processes. Mitochondria are considered as the powerhouses of the cell, which synthesizes energy in the form of ATP.

(b1)

Summary Introduction

To determine: The weight of $\text{ATP}$ used by a human adult in $24$ hours.

Summary Introduction

To determine: The percentage of the body weight which is represented by the weight of $\text{ATP}$ used by a human adult in $24$ hours.

(c)

Summary Introduction

To explain: The apparent contradiction regarding the fact that the adults synthesize large amounts of ATP daily, their weight, structure, and composition do not change significantly during 24 hours.
