Question

The given figure is related with myosin monomer (meromyosin). identify the parts labelled from A to C and select the correct option.

• A. A - Head. B - Cross arm C - GTP binding sites
• B. A - Cross arm B - Head C - $CA^{+2}binding sites
• C. A - Head B - Cross arm C - ATP binding sites
• D. A - Cross arm B - Head C - ATP binding sites

Answer 1

Answer: (C)

A - Head B - Cross arm C - ATP binding sites

Myosin molecules are composed of a head, neck, and tail, a represents the head, b represents cross bridges, c represents ATP binding site.

So, the correct option is 'A - Head B - Cross arm C - ATP binding sites'.
