Answer:
a. Protein is a major component of body structures.
Explanation:
Proteins are large, complex molecules made up of amino acids. They play a crucial role in the structure and function of our bodies. Here's why option a is the correct answer:
a. Protein is a major component of body structures: Proteins are the building blocks of tissues in our body, such as muscles, bones, skin, and organs. They provide structural support and help maintain the integrity of our body.
b. Supplies 9kcal per gram: This statement is incorrect. Protein supplies 4 calories per gram, not 9. It is carbohydrates and fats that provide 9 calories per gram.
c. Functions as a solvent: This statement is incorrect. Proteins do not function as solvents. They are involved in various functions such as enzyme catalysis, transport of molecules, immune response, and cell signaling, but not as solvents.
d. Is the body's main source of fuel during physical activity: This statement is also incorrect. While protein can be used as an energy source, it is not the body's main source of fuel during physical activity. Carbohydrates and fats are the primary sources of energy during physical activity.
In summary, protein is a major component of body structures and plays a vital role in maintaining the structure and function of our body.
