Please complete the following sentence.

Answer 1

Answer:

c. rich in cholesterol, sphingolipids, and GPI-linked proteins. The bilayer is thicker in the raft domains than in the surrounding membrane.

Explanation:

Membrane rafts (or lipid rafts) are sections of a celular membrane. They help compartmentalize certain cellular processes.

As the lipid part of its name implies, they are enriched in cholesterol, sphingolipids and GPI-linked proteins. Because it is enriched in such species, it is also thicker than in the surrounding membrane.
