Question

to repair a cell membrane, which macronutrient would supply the needed building blocks?
protein
amino acids
fats
carbohydrates
nucleic acids

Explanation:

Cell - membranes are composed mainly of lipids (fats). Fats, specifically phospholipids, are the major structural components of cell - membranes. Proteins are involved in functions like transport and signaling in the membrane but are not the main building blocks for repair. Amino acids are the building blocks of proteins. Carbohydrates are mainly for energy and cell - recognition functions. Nucleic acids are for storing and transmitting genetic information.

Answer:

C. fats
