Question

PLEASE HELP!!!!! Fill in the both blanks: In skeletal muscle, DHP receptors are found in the____ membrane, while ryanodine receptors are found in the____ membrane.
top(1) row: sarcoplasmic reticulum, T-tubule, Mitochondrial, Nerve cell bottom

(2) row:Axon terminal, Sarcolemma, T-tubule, Terminal Cistern ​

Answer 1

Answer:

Row 1

T-tubule

Dihydropyridine (DHP) receptors of the transverse tubule membrane play two roles in excitation-contraction coupling in skeletal muscle: (a) they function as the voltage sensor which undergoes fast transition to control release of calcium from sarcoplasmic reticulum, and (b) they provide the conducting unit of a slowly ...

Row 2

Sarcolemma

Ryanodine receptors (RyRs) are located in the sarcoplasmic/endoplasmic reticulum membrane and are responsible for the release of Ca2+ from intracellular stores during excitation-contraction coupling in both cardiac and skeletal muscle.
