Chapter 3, Problem 9P

Interpretation Introduction

To Calculate:

Weight of creatine phosphate that would need to be consumed each day by a typical adult human if creatine phosphate could not be recycled should be calculated. If creatine phosphate were recyclable how many times would each creatine phosphate molecule need to be turned over or recycled each day should be calculated. The calculations should be repeated glycerol-3-phosphate.

Introduction:

ATP is the universal energy carrier of human body. An average adult human consumes around $\text{11700 kJ}$per day. And efficiency of metabolic pathways which leads to ATP synthesis is $\text{50 \%}$. Therefore from $\text{11700 kJ}$which a person consumes as a food, only about $\text{5860 kJ}$will end up in ATP. Free energy yield by the hydrolysis of ATP is $\text{50 kJ/mol}$under cellular conditions. Therefore according to the calculations average adult human will consume around $\text{65 kg}$ATP per day. But there is a highly efficient ATP/ADP recycling system in the human body which ATP recycles around $\text{1300}$times a day.
