- The presence of calcium in the sarcoplasm is directly responsible for exposing the binding sites on actin.
- Rigor mortis occurs after death because detachment of crossbridges does not occur due to the lack of ATP
<h3>What is Sarcoplasm?</h3>
This is defined as the the cytoplasm of striated muscle cells in living organisms .When calcium is present, the binding sites on actin are exposed.
Rigor mortis occurs after death and involves stiffening of the muscle tissue because detachment of cross bridges does not occur due to the lack of ATP.
