Question

The globular head of a heavy meromyosin part of meromyosin has: (A) Actin binding sites (B) ATP binding sites (C) ATPase enzyme activity (D) All of the above

Tardigrade Admin · Accepted Answer

Each meromyosin has two parts, the heavy meromyosin (HMM) and light meromyosin (LMM). The heavy meromyosin consist of a globular head and a short arm. The globular head is an active ATPase enzyme and has binding sites for ATP and active sites for actin.
