Question

Hypothetically, if a muscle were stretched to the point where thick and thin filaments no longeroverlapped, ________.A) maximum force production would result because the muscle has a maximum range of travelB)no muscle tension could be generatedC)cross bridge attachment would be optimum because of all the free binding sites on actinD) ATP consumption would increase because the sarcomere is "trying" to contract

Answer 1

Answer:

The answer is B- no muscle tension could be generated

Explanation:

During contraction cross  bridges are formed by the myosin thick filaments grabbing on to the actin thin filaments. . The overlap of the thick and thin filaments allows myosin to bind to actin. As more bridges are formed, more myosin will pull on actin and more tension will be produced.  Muscle tension is a condition in which the body remains semi-contracted for a longer time, it is caused when muscles contracts and do not release.

However, if the muscles are stretched to a point where the thick and thin filaments no longer overlap there will be no muscle tension generated.
