Question

the cytoskeleton of a cell is comprised of which of the following mac
carbohydrates
proteins
lipids
nucleic acids

Explanation:

The cytoskeleton is a network of protein filaments (such as microtubules, microfilaments, and intermediate filaments) that provide structural support, help in cell movement, and assist in intracellular transport. Proteins are the building blocks of these filaments. Carbohydrates are mainly for energy storage (e.g., starch, glycogen) or cell - surface recognition. Lipids form the cell membrane (phospholipids) and are also for energy storage (fats). Nucleic acids (DNA and RNA) store and transmit genetic information.

Answer:

Proteins
