Why is it necessary for ATP to be used in the energy-investment phase of glycolysis?
A) Adding the phosphate activates the glucose, making it easier to break it apart.
B) Adding the phosphate to the glucose makes it more stable and less likely to break apart.
C) There is no purpose to adding the phosphate to the glucose; it just happens that way.
D) The addition of the phosphate is necessary to produce NADH.
E) The energy that is released when ATP becomes ADP is harnessed and used to pump hydrogen ions across the mitochondrial membrane.

Adding a phosphate group to glucose during the energy-investment phase of glycolysis activates the glucose molecule, making it more reactive and thus easier to break down into smaller molecules. This is a crucial step for the subsequent reactions in the glycolytic pathway.
