Biology Question on locomotion and movement
Actin binding sites are located on:
A
Troponin
B
Tropomyosin
C
Meromyosin
D
Both tropomyosin and meromyosin
Answer
Meromyosin
Explanation
Solution
Myosin has two fragments, light meromyosin (LMM) and heavy meromyosin (HMM). HMM consists of two globular sub fragments (S-l) and one rod shaped fibrous sub fragment (S-2). Each S-l segment contains an ATPase site and a binding site for actin.
