In Skeletal Muscle Depolarization of the T Tubule Membrane Causes

In skeletal muscle depolarization of the T tubule membrane causes

A) activation of Ca²⁺ ATPase pumps which triggers a rise in intracellular calcium levels
B) dihydropyridine to bind calcium channel receptors which triggers a rise in intracellular calcium levels.
C) activation of stretch-activated Ca²⁺ channels which triggers a rise in intracellular calcium levels.
D) activation of dihydroxypyridine receptors in membrane of the T tubule which triggers a rise in intracellular calcium levels.
E) ryanodine to bind calcium channel receptors which triggers a rise in intracellular calcium levels.
