Chapter 6.3, Problem 2CS
Summary Introduction
To determine: The reason that feedback inhibition which occurs in the cell during the process of glycolysis is beneficial to the cell.
Introduction: Glycolysis is an important event that takes place inside the cell. During the process of glycolysis, carbohydrates are converted to two molecules of pyruvate. The process of feedback inhibition occurs during the glycolysis process in the cell.

Hydrolysis is a reaction in which a
large molecule is split into two smaller
molecules upon the addition of water,
H₂O.
Adenosine triphosphate, ATP, has one
more inorganic phosphate group than
does adenosine diphosphate, ADP.
ADP has two phosphate groups,
whereas adenosine monophosphate,
AMP, has one.
Consider whether P; should be placed
on the left or the right side of the
reaction arrow in each reaction.
