Question

2.20 unit 2: biochemistry summative test
which of the following would provide the most energy to a cell as a source of energy?
○ carbohydrates
○ lipids
○ nucleic acids
○ protein

Explanation:

Lipids are a concentrated source of energy. When metabolized, lipids yield more energy per gram compared to carbohydrates, proteins, and nucleic acids. Carbohydrates are a quick - energy source but not the most energy - dense. Proteins are mainly for building and repairing tissues and are not the primary high - energy source. Nucleic acids (DNA and RNA) are involved in genetic information storage and transfer, not energy provision.

Answer:

lipids
