Question

use the same article to answer the following questions. muscle contraction what happens if there is not enough atp available? which of the following did you include in your response? check all that apply. muscles cannot contract. muscle fibers become locked in a state called rigor. muscle contraction is impaired. the myosin action cross bridges cannot detach properly, leading to muscle stiffness and inability to relax properly as calcium re uptake into the sarcoplasmic reticulum is a affected due to lack of atp

Explanation:

When there is not enough ATP, myosin - actin cross - bridges can't detach properly and calcium re - uptake into the sarcoplasmic reticulum is affected, leading to muscle stiffness and inability to relax. This state is known as rigor. Muscles don't completely lose the ability to contract but contraction is impaired.

Answer:

Muscle fibers become locked in a state called rigor.
