Chapter 4, Problem 29RQ

Summary Introduction

To analyze:

The equilibrium constant (K_eq) of the equation:

Adenosine triphosphate (ATP) → Adenosine monophosphate (AMP) + 2 inorganic phosphate (P_i). The standard free energy (∆G°’) values are as follows:

$\begin{array}{c}\text{ATP}\to {\text{AMP+PP}}_{\text{i}}\left(-32.2\text{kiloJoule/mole}\right)\\ {\text{PP}}_{\text{i}}\to {\text{2P}}_{\text{i}}\left(\text{-33}\text{.5kJ/mol}\right)\end{array}$

Introduction:

The energy currency of the living cell is called ATP. It is found in every organism. It is utilized in doing any metabolic work. It is then hydrolyzed into ADP or AMP. Standard free energy is the energy released or utilized at 25˚C (298 Kelvin) and 1 atm pressure.
