What is the role of Myosin light chain kinase (MLCK) in muscle contraction?

Back

MLCK phosphorylates myosin light chains, which is essential for muscle contraction.

Front

What is the function of baroreceptors?

Back

Baroreceptors detect changes in blood pressure.

Front

What is the primary function of osmoreceptors?
