Energy for muscle contraction is provided when ATP is broken down.

Question

Quizplus · Accepted Answer

ATP (adenosine triphosphate) is broken down to release energy for muscle contraction. This process results in the formation of ADP (adenosine diphosphate) and inorganic phosphate. The energy released from the ATP breakdown is used to power muscle contractions, which involve the sliding of actin and myosin filaments within muscle fibers. Once the ATP is used up, it must be replenished through processes like cellular respiration or fermentation, which generate ATP from glucose or other fuel sources.
