Question: 1 / 400

What role do proteins play in the body?

Immediate energy production

Support growth and development

Proteins play a crucial role in supporting growth and development in the body. They are essential macromolecules that serve as the building blocks for tissues, including muscles, organs, skin, and enzymes. Proteins are involved in numerous biological processes, such as repairing and building tissues, synthesizing hormones, and facilitating biochemical reactions.

While immediate energy production is primarily associated with carbohydrates and fats, and storing excess energy is primarily a function of fats, proteins can provide energy when necessary, but that's not their primary role. Additionally, proteins do not directly assist in hydration; instead, hydration is predominantly maintained through water and electrolyte balance. Thus, supporting growth and development accurately represents the essential function of proteins in the body.
