What are the primary building blocks of body tissue?

• A. Fats
• B. Carbohydrates
• C. Proteins
• D. Minerals

Answer: (C)

The primary building blocks of body tissue are proteins. Proteins are essential macromolecules made up of amino acids, which are linked together in specific sequences to form various types of proteins that play critical roles in the structure, function, and regulation of the body’s tissues and organs.

In particular, proteins are fundamental components of muscle, skin, enzymes, and hormones. They provide structure to cells and tissues, facilitate biochemical reactions, and help transport molecules within the body. Collagen and elastin, for example, are proteins that provide strength and elasticity to skin and connective tissues.

While fats, carbohydrates, and minerals also play important roles in bodily functions, they do not serve as the primary building blocks of tissue in the same way that proteins do. Fats are primarily involved in energy storage and cellular membranes, carbohydrates serve mostly as an energy source and structural components for some cells, and minerals are vital for various biochemical processes and structures (like bone) but are not building blocks in the context of tissue formation as proteins are.
