Question

What is the structure of the muscle cell?

1) Nucleus
2) Mitochondria
3) Transverse (T) tubules
4) Golgi apparatus

Answer 1

Muscle cells have a specific structure that enables them to contract and perform their functions. Key components of a muscle cell include the nucleus, mitochondria, and transverse (T) tubules. Hence, 1, 2 and 3 are correct.

Step-by-step explanation:

Muscle cells, also known as muscle fibers, have a specific structure that enables them to contract and perform their functions. The structure of a muscle cell includes various components:

1. Nucleus: Muscle cells have one or more nuclei that are usually located on the periphery of the cell.
2. Mitochondria: These organelles are responsible for producing energy in the form of ATP to support muscle contractions.
3. Transverse (T) tubules: T tubules are invaginations of the sarcolemma, the muscle cell membrane. They allow electrical impulses to penetrate the interior of the cell, triggering muscle contractions.

The Golgi apparatus, on the other hand, is not a component of muscle cells.
