Question

based on the image below, which macromolecule is embedded in the plasma membrane and facilitates transport?
proteins
carbohydrates
nucleic acids
lipids

Explanation:

Proteins in the plasma membrane play crucial roles in facilitating transport. They can act as channels or carriers, allowing specific molecules to pass through the membrane. Lipids form the basic structure of the membrane (the lipid bilayer), but it is the proteins that are mainly responsible for transport functions. Nucleic acids (like DNA and RNA) are not part of the membrane structure involved in this transport. Carbohydrates in the membrane are often involved in cell - cell recognition rather than transport.

Answer:

Proteins
