alleryThe two parts of a meromyosin are called
Athick and thin meromyosin
Balpha and beta meromyosin
Cheavy and light meromyosin
Dlong and short meromyosin
Answer & Solution
Correct answer: C. heavy and light meromyosin
1. Each myosin monomer has two important parts.
2. One is a globular head with a short arm, and the other is a tail.
3. The former is the heavy meromyosin, abbreviated HMM.
4. The latter is the light meromyosin, abbreviated LMM.
5. The head of the heavy meromyosin is what forms the cross bridge with actin.
