A. Eating more creatine leads to more creatine phosphate stores in muscles, which then equates to larger energy stores available for short, explosive bouts of energy use.
B. Creatine in the blood allows the body to absorb more oxygen, which helps to fuel ATP production in the muscle cells.
C. Creatine increases the speed with which neural signals reach the muscle.
D. Unlike oxidative phosphorylation, ATP can be formed within a fraction of a second from creatine phosphate sources, since only one enzymatic reaction is involved in this energy transfer.

Option A
