MGD Lecture 7: Ne 2024 by Dr. Asaad Alasady

Stimulation of calcium-activated potassium channels

Inhibition of myosin light chain kinase

Activation of myosin light chain phosphatase (correct)

Inhibition of voltage-gated calcium channels

High velocity of contraction

Fast-twitch, high-force generation

Slow-twitch, low-force generation (correct)

Long duration of contraction

Calcium binds to and activates calmodulin, leading to smooth muscle relaxation

Calcium binds to and activates troponin, leading to smooth muscle contraction

Calcium binds to and activates calmodulin, leading to smooth muscle contraction (correct)
