How would muscle contractions be affected if ATP was completely depleted in a muscle fiber?
How would muscle contractions be affected if ATP was completely depleted in a muscle fiber? Because ATP is required for myosin to release from actin, muscles would remain rigidly contracted until more ATP was available for the myosin cross-bridge release. This is why dead vertebrates undergo rigor mortis.
