Question

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?

Answer 1

Muscle cells regenerate ATP through aerobic and anaerobic respiration, as well as the breakdown of creatine phosphate.

Step-by-step explanation:

Muscle cells get the ATP they need to contract and move you through a process called ATP regeneration. Although there is little ATP in your bloodstream, muscle cells have a high concentration of mitochondria that produce ATP. When there is enough oxygen available, aerobic respiration occurs, generating ATP from glucose. However, during intense exercise or when oxygen supply is limited, anaerobic respiration takes place, converting glucose into lactic acid and generating ATP. Another method of ATP regeneration is through the breakdown of creatine phosphate, which can release energy to regenerate ATP.

Answer 2

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
