185) The thick filament of the myofibril is composed of approximately 250
_________ molecules.
a) titin
b) troponin
c) tropomyosin
d) actin
e) myosin

Solution

Solution:
(e) The thick filament of the myofibril is composed of approximately 250 myosin molecules.Filaments of myofibril are composed of mainly two types.One is thick filament which is consist of myosin and other is thin filament which is made up of action.All these protein like myosin,actin composed together to form myofibril.
