How does the shape of proteins in muscle fibers affect their function?

Question

Quizplus · Accepted Answer

The shape of proteins in muscle fibers is long, which allows the muscle fibers to contract and relax. This is essential for the function of muscles in movement and maintaining posture. Muscles are made up of many fibers that contain actin and myosin proteins, which interact to cause muscle contraction. The long shape of these proteins allows for the sliding of actin and myosin filaments, which shortens the muscle fiber and causes muscle contraction.
