Muscle cells can use the _____ energy system to obtain energy.

Question

Quizplus · Accepted Answer

Muscle cells can use the lactic acid energy system (anaerobic glycolysis) to obtain energy in the absence of oxygen. During intense muscular activity, the body's supply of oxygen may become limited, so muscle cells convert glucose to lactic acid as an alternative source of energy. This process is relatively inefficient and can only sustain muscle activity for a short period of time. The other choices, oxaloacetate, carbon, and GTP, are not directly involved in energy production in muscle cells.
