Question

Match the channel type with the appropriate description.

Allows calcium movement into the cell during the late spontaneous depolarization in autorhythmic cells.

A) voltage-gated sodium channels
B) potassium channels
C) funny channels
D) T-type calcium channels
E) L-type calcium channels

Answer 1

L-type calcium channels allow calcium movement into the cell during the late spontaneous depolarization in autorhythmic cells.

Step-by-step explanation:

The channel type that allows calcium movement into the cell during the late spontaneous depolarization in autorhythmic cells is L-type calcium channels (E).

These channels open and allow calcium ions (Ca²+) to enter the cell, further depolarizing it. The influx of calcium ions contributes to the autorhythmicity properties of cardiac muscle.
