Question
Chapter 13.3, Problem 1TQ
Summary Introduction
To analyze:
1. The value of ΔG°’ (Gibbs free energy at standard conditions), when ATP (Adenosine triphosphate) phosphorylates glucose and pyruvate.
2. Phosphorylation of ATP to pyruvate and the requirement of additional energy in this reaction.
Introduction:
Reactions are carried out in a stepwise manner to save energy for different cell functions and biosynthesis. For this purpose, the cell uses energy carriers. These molecules store and release energy during various reactions. They act as a source of energy for a variety of biochemical reactions. The ATP and NADPH (Nicotinamide adenine dinucleotide) are examples of energy carriers.
