Questions: Multiple Choice Question Maintaining cell membranes, insulating the body against cold temperatures, cushioning the body against, bumps and blows, and prod all traits of which nutrient? Carbohydrates Vitamins Lipids Proteins

The answer is the third one (C): Lipids.

Explanation for each option:

• Carbohydrates: These are primarily used by the body as a source of energy. They do not play a significant role in maintaining cell membranes, insulating the body, or cushioning against physical impacts.

• Vitamins: These are essential nutrients that the body needs in small amounts for various functions, including immune function and bone health. However, they do not provide structural or insulating functions like those described in the question.

• Lipids: These are fats and oils that are crucial for maintaining cell membranes, insulating the body against cold temperatures, and cushioning the body against bumps and blows. Lipids are the correct answer because they perform all the functions mentioned in the question.

• Proteins: These are essential for building and repairing tissues, making enzymes and hormones, and supporting immune function. While important, they do not primarily serve the functions listed in the question.

In summary, lipids are the nutrient responsible for maintaining cell membranes, insulating the body, and providing cushioning.
