The thick filament in muscles is polymerised protein of

Options

A. meromyosins
B. actins
C. troponins
D. tropomyosins

Answer

To answer the question about the thick filament in muscles, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Muscle Structure**:
- Muscles are made up of structures called myofibrils.
- Myofibrils consist of two types of filaments: thick filaments and thin filaments.

2. **Identifying the Filaments**:
- The thin filament is primarily composed of a protein called actin.
- The thick filament is primarily composed of a protein called myosin.

3. **Composition of Myosin**:
- Myosin is a polymerized protein, meaning it is made up of smaller units called monomers.
- The monomers that make up myosin are known as meromycins.

4. **Conclusion**:
- Therefore, the thick filament in muscles is a polymerized protein of meromycins.

### Final Answer:
The thick filament in muscles is a polymerized protein of **meromycins**.
