What is the difference between T-calcium channels and L-calcium channels?
a. T-channels can inactivate (close) after a few milliseconds; L-channels are incapable of inactivation.
b. T-channels dictate presynaptic cardiac transmission; L-channels are involved in postsynaptic cardiac transmission.
c. T-channels flux calcium into a cardiac muscle cell; L-channels flux calcium out of cardiac muscle.
