Question

Quizplus · Accepted Answer

Anaerobic energy production, specifically through the process of glycolysis, is the primary source of energy during high intensity activities such as sprinting or weightlifting. This process does not require oxygen and can produce ATP quickly, but only for a short period of time before fatigue sets in. Aerobic energy production is more efficient and sustainable, but takes longer to produce ATP and cannot keep up with the demand during high intensity activities. The Krebs cycle contributes to ATP production by substrate level phosphorylation regardless of intensity, but its contribution is relatively small compared to anaerobic and aerobic energy production.
