The correct pairing from the provided options is:
B: lipids: provide slow, long-term energy to cells.
Here's a brief explanation for each of the options:
A. Proteins: provide quick, short-term energy to cells - This is incorrect as proteins are primarily used for structure, function, and regulation of the body's cells, tissues, and organs, rather than for quick energy.
B. Lipids: provide slow, long-term energy to cells - This is correct as lipids (fats) serve as a significant energy reserve and provide energy over a longer period.
C. Nucleic acids: digest dead cells - This is incorrect because nucleic acids (DNA and RNA) are involved in storing and transmitting genetic information, not in digestion.
D. Carbohydrates: store genetic information - This is incorrect as carbohydrates primarily function to provide immediate energy and structural support, whereas nucleic acids are responsible for genetic information storage.
Therefore, option B is the only correct pairing.
