Question

question: 1 which of the following best compares lipids and carbohydrates?
a. carbohydrates provide cells with the structures to build and repair cells, while lipids code for the cell’s genetic information.
b. carbohydrates supply cells with fast, easy to use energy, while lipids supply cells with more, long - term energy.
c. lipids supply cells with fast, easy to use energy, while carbohydrates supply cells with more, long - term energy.
d. lipids provide cells with the structures to build and repair cells, while carbohydrates code for the cell’s genetic information.

Explanation:

• Option A: Proteins (not carbohydrates) are for building/repairing cells, and nucleic acids (not lipids) code genetic info. Eliminate A.
• Option B: Carbohydrates (like glucose) are quick energy sources. Lipids (like fats) store long - term energy. This matches their roles.
• Option C: Swaps the energy roles of carbohydrates and lipids. Carbohydrates are fast energy, lipids are long - term. Eliminate C.
• Option D: Proteins (not lipids) build/repair cells, nucleic acids (not carbohydrates) code genetic info. Eliminate D.

Answer:

B. Carbohydrates supply cells with fast, easy to use energy, while lipids supply cells with more, long - term energy.
