D)they conserve actin and myosin in cold weather.

Question

Quizplus · Accepted Answer

Skeletal muscles generate heat when they contract, and the more active they are, the more heat is released into the body. This is known as thermogenesis and helps to maintain body temperature in cold environments or during physical activity. Option A is incorrect because the heat generated from muscle activity is released, not used up. Option C is incorrect because excess myosin is not metabolized to yield heat, and option D is irrelevant to the question.
