Statement A : Each myosin is a polymerised protein, many meromyosins constitute one thin filament (myosin). Statement B : The globular head of actin is an active sites for myosin .
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
Each myosin (thick) filament is also a polymerised protein. Many monomeric proteins called Meromyosins constitute one thick filament. The globular head of meromyosin has an active site for actin.
