Question: 1 / 400

Which nutrient's function is primarily to build and repair tissue?

Carbohydrates

Vitamins

Protein

The function of protein is primarily to build and repair tissue, making it essential for growth and maintenance in the human body. Proteins are made up of amino acids, which are the building blocks needed for the synthesis of muscle, skin, organs, and other bodily tissues. When the body sustains injury or undergoes growth, the demand for protein increases to support healing and development.

In contrast, carbohydrates primarily serve as a source of energy for the body, while fats also provide energy but are crucial for hormone production and cell membrane structure. Vitamins, although essential for various bodily functions, do not directly contribute to the building or repairing of tissues, but rather support metabolic processes and immune function. This distinction highlights the critical role that protein plays in tissue health and regeneration.
