Muscle cells contract using ATP. There is little ATP in your blood stream. How do your muscle cells get ATP they need to contract and move you?

Respuesta :

Answer:  Aerobic ATP Production

Explanation:  During everyday activities and light exercise, the mitochondria of muscle fibers produce ATP in a process called aerobic respiration. Aerobic respiration requires the presence of oxygen to break down food energy (usually glucose and fat) to generate ATP for muscle contractions
