Question

If no ATP is present in the muscle cell what would be the likely result?
a. The myosin would not be able to attach to the actin
b. The muscle would not be able to shorten
c. The myosin would not be able to let go of the actin
d. ATP is not needed in the muscle cell

Answer 1

Answer: c. The myosin would not be able to let go of the actin

Explanation:

Muscles consists of two proteins called actin and myosin and responsible for muscle contraction.

Myosin is ATP dependant and when ATP binds to it, it is able to release the actin.

This will allow the actin and myosin to seperate from each other thus leading to muscle contraction
