Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The site which meromyosin possesses to bind to actin is
A
ATP binding site
B
Myosin binding site
C
Actin binding site
D
Electron binding site
Explanation: 

Detailed explanation-1: -As we already mentioned that the head of meromyosin has two binding sites for ATP and active sites for actin. So, our first option is Troponin.

Detailed explanation-2: -The location of the myosin binding is an extended region encompassing the junction of domains 3/4 and domain 4a (residues 622-714, human; 566-657, chicken gizzard). Tropomyosin binds in a smaller region within domain 4a of caldesmon (residues 663-714, human; 606-657 chicken gizzard).

Detailed explanation-3: -Myosin is a major component of thick filaments. They are composed of a head, neck, and tail domain. The head contains ATPase and has ATP binding sites and active sites for actin (actin binding sites).
