Question

Which  ONE  of the following
statements about the interaction of the voltage sensor and the ryanodine
receptor in skeletal muscle is  CORRECT ? (Lecture: skeletal muscle, Chapter: excitation-contraction coupling)

Answer

The voltage sensor depolarizes the SR membrane which
opens the calcium release channels.

Answer

Calcium entering through the voltage
sensor activates the ryanodine receptor via calcium-induced calcium release.

Answer

The  ryanodine receptor is opened
by the voltage sensor.

Answer

The  voltage sensor is located in
the membrane of the sarcoplasmic reticulum.

Answer

The voltage sensor is a
voltage-gated sodium channel in the sarcolemma.
