Question

1. what types of molecules make up the cell membrane? select all that apply. 4) nucleic acids carbohydrates proteins lipids

Explanation:

The cell membrane is a biological structure. Carbohydrates are present as carbohydrate groups (e.g., glycoproteins, glycolipids). Proteins (integral and peripheral) are embedded in or associated with the membrane. Lipids (phospholipids, cholesterol) form the basic framework. Nucleic acids (like DNA, RNA) are mainly in the nucleus (not a major component of the cell membrane structure shown here).

Answer:

Carbohydrates, Proteins, Lipids
