What is the relationship between meromyosins and the thick filament in a myofibril?
What is the relationship between meromyosins and the thick filament in a myofibril?
Meromyosins are the main component of the thick filament
Meromyosins run close to the thick filament
Meromyosins are distributed at regular intervals on the thick filament
Meromyosins have no relationship with the thick filament
Solution
Myosin makes up the thick filament and is a polymerised protein. It is made up of meromyosin, a monomeric protein. Meromyosin has 2 parts: a globular head with short arm, called heavy meromyosin, and the tail, called light meromyosin.
