What are the basic materials and building blocks for body tissues?

1. Carbohydrates

2. Fats

3. Proteins

4. Vitamins

The correct answer is: Proteins

Proteins are indeed the basic materials and building blocks for body tissues, which is why this choice is correct. Proteins are composed of amino acids, which are essential for a wide range of bodily functions including the growth, repair, and maintenance of tissues. They contribute to the structure of cells and are crucial for the development of muscles, skin, hair, and nails. While carbohydrates and fats also play important roles in the body—carbohydrates provide energy and fats contribute to cell membrane structure and energy storage—they do not serve as the primary structural components of tissues like proteins do. Vitamins are organic compounds that are vital for various metabolic processes but do not directly contribute to the building of body tissues in the same way proteins do. Understanding the distinct functions of these nutrients highlights why proteins are considered the fundamental building blocks for body tissues.
