Which of the Following Statements About Lipids is Accurate

Question

Which of the following statements about lipids is accurate?
A) Because lipids are converted to cholesterol, they should be avoided in the diet.
B) Lipids contribute to cellular structure.
C) Lipids are less energy dense as compared to sucrose.
D) Lipids are the body's first choice for energy.

Accepted Answer

Lipids contribute to cellular structure by forming cell membranes and aiding in the transport of molecules in and out of cells. While lipids can be converted to cholesterol, not all lipids are equal in their impact on cholesterol levels, and some types of lipids, such as unsaturated fats, can actually have a positive effect on cholesterol levels. Lipids are actually more energy dense than sucrose, containing 9 calories per gram compared to sucrose's 4 calories per gram. While lipids can be used for energy, they are not the body's first choice as the body typically prefers to use carbohydrates for energy production.
