Describe the main differences in the way that skeletal and smooth muscles contract

Expert Solution

Smooth muscles contractions:

Skeletal muscle contractions:

smooth muscles contractions involve calcium and calmodulin binding.

Skeletal muscle contractions involve troponin and tropomyosin,myosin head.

Describe at least FOUR processes in neurons and/or myocytes (muscle cells: skeletal, smooth, & cardiac) in which Calcium Ions (Ca++) function as important intracellular secondary messengers. Diagram how calcium exerts its effect on cells in each of these cases (what molecules does it act upon, and what is the result?).
