At peak levels of muscle exertion,the mitochondria can supply ________ of the energy required by the muscle.

Question

Quizplus · Accepted Answer

At peak levels of muscle exertion, the mitochondria can only supply about one-third of the energy required by the muscle. This is because at high levels of exertion, the muscle switches to anaerobic respiration, which does not rely on mitochondria and produces energy faster but less efficiently. As a result, the majority of energy production comes from other sources such as glycogen stored in the muscle.
