Question

Quizplus · Accepted Answer

The dihydropyridine (DHP) receptor, also known as the L-type calcium channel, is responsible for detecting the action potential traveling along the t-tubule. It is located in the plasma membrane and undergoes a conformational change upon binding to an incoming action potential. This change leads to the opening of the nearby ryanodine receptor, allowing calcium ions to flow into the cell and trigger muscle contraction. The other options listed are not involved in this process.
