Question

State whether the following statements are true or false.
The functional unit of the contractile system in the striped muscle is sarcomere.

• A. True
• B. False

Answer 1

The correct option is A True

A sarcomere is the basic unit of muscle tissue in both cardiac and skeletal muscle. Myofibril activity is required for muscle contraction on the molecular level. When ATP binds to myosin, it separates from the actin of the myofibril, which causes a contraction.

So, the correct option is 'True'.
