Question

Quizplus · Accepted Answer

Creatine phosphate transfer is the first metabolic pathway by which ATP is made in an active muscle cell. Creatine phosphate donates a phosphate group to ADP to form ATP, providing a quick source of energy for muscle contraction. Glycolysis, the aerobic pathway, Krebs cycle, and electron transport system all produce ATP, but take longer and require oxygen, making creatine phosphate transfer the primary initial energy source.
