The structural level in which the muscle produces the contraction is known as the muscle fiber.
<h3>What is a muscle fiber?</h3>
A muscle fiber is a single muscular cell that is able to contract by using specialized proteins such as filaments of myosin and actin.
This unit (muscle fiber) is able to contract both in vivo and in vitro by establishing suitable environmental conditions (e.g., proper calcium levels).
In conclusion, the structural level in which the muscle contracts is the muscle fiber.

Explanation:
The major nutrients required by humans in food are carbohydrates, proteins, fats, vitamins, and minerals. Our food also has dietary fibers and water. Dietary fibers or fibers are also known as roughage. Fibers are present mainly in plant products such as whole grains, pulses, fruits and vegetables. Fibers only add bulk and do not provide any nutrients to us. However, dietary fibers help the body get rid of undigested food.
Answer:
Enzymes are biological catalysts that increase the rate of chemical reactions inside cells by lowering the activation energy required for the reaction to proceed. In nature, exergonic reactions do not require energy beyond activation energy to proceed, and they release energy.
