List two muscle contractile proteins

Myosin and Actin

15

List two muscle regulatory proteins

troponin and tropomyosin

16

List three muscle cytoskeleton proteins

Titin, Nebulin, and C protein

17

List four major nutrients found in muscle, that meat is considered a good source.

18

Explain how striated muscle cells become multi-nucleated.

Cell fuse together and overlap to become muscle fiber and in a muscle they become multi - nucleated.
