Question

question 9
macronutrients are.
a nutrients that are large in terms of molecular structure.
b nutrients that our body can’t make.
c nutrients our body needs in large amounts.
d molecules that include proteins, carbohydrates, and nucleic acids.
e a and b

Explanation:

To determine the correct answer, we analyze each option:

• Option A: Macronutrients are not defined by molecular size alone. For example, water is a macronutrient but has a simple molecular structure. So A is incorrect.
• Option B: Some macronutrients (like non - essential amino acids) can be made by the body. So B is incorrect.
• Option C: By definition, macronutrients are nutrients (such as carbohydrates, proteins, and fats) that the body needs in large amounts. This matches the definition of macronutrients.
• Option D: Macronutrients typically include carbohydrates, proteins, and fats, not nucleic acids. So D is incorrect.
• Option E: Since A and B are incorrect, E is also incorrect.

Answer:

C. nutrients our body needs in large amounts.
