Because skeletal muscle contractions demand large quantities of ATP, skeletal muscles have
A) a rich nerve supply.
B) a rich vascular supply.
C) very few mitochondria.
D) little need for oxygen.
E) all of the above

Question

Quizplus · Accepted Answer

Skeletal muscles have a rich vascular supply to deliver oxygen and nutrients, such as glucose and fatty acids, to provide the ATP needed for muscle contractions. A rich nerve supply is also necessary for motor neuron activation, but it is not directly related to ATP production. Skeletal muscles have a high density of mitochondria to support ATP production. Oxygen is needed for efficient ATP production, so skeletal muscles have a high demand for oxygen.
