Question: 1 / 400

What is the primary role of proteins in the body?

Providing instant energy

Building and repairing tissues

The primary role of proteins in the body is building and repairing tissues. Proteins are made up of amino acids, which are essential for numerous bodily functions. They serve as the building blocks for muscles, skin, organs, and various cellular structures, facilitating growth and recovery after injury or stress. When the body undergoes changes due to exercise, injuries, or metabolic processes, proteins play a crucial role in synthesizing new tissues and repairing damaged ones.

This role is vital not only in terms of physical development and maintenance but also in producing enzymes and hormones that regulate numerous physiological processes. While energy production, fat storage, and sensory perception are important functions within the body, they are not the primary function of proteins when it comes to overall tissue health and bodily repair.
