What is the main energy source for muscular function?

Question

Quizplus · Accepted Answer

Adenosine triphosphate (ATP) is the main energy source for muscular function. ATP is produced through the breakdown of carbohydrates and fats, and provides energy for muscle contraction. Oxygen and vitamins/minerals are also important for muscular function, but they are not the main energy source. Fat can be used as an energy source for long-duration, low-intensity exercise, but it is not the main source of energy for muscular function.
