Answer 1

Muscle fibers express muscle specific products which are proteins and enzymes needed for muscle contraction.

Step-by-step explanation:

Muscle fibers express a number of muscle specific products which give the muscle its ability to contract. These muscle specific products are primarily proteins and enzymes that are required for muscle contraction. For example, actin and myosin are contractile proteins that are responsible for muscle movement.

Muscle fibers also have specialized structures such as the sarcolemma (plasma membrane), sarcoplasm (cytoplasm), and sarcoplasmic reticulum (smooth endoplasmic reticulum) that play important roles in muscle contraction.
