Question

State whether the following statements are true or false.
Actin is actually a globular protein that assembles as a long beady structure consisting of two helical chains.

• A. True
• B. False

Answer 1

The correct option is A True

Skeletal muscle is composed of muscle fibres which have smaller units called myofibrils. There are three types of proteins make up each myofibril; they are contractile, regulatory and structural proteins. By contractile proteins, we mean actin (thin filament), a globular protein assembling with a long beady structure consisting chains and myosin (thick filament).

So, the correct option is 'True'.
