Question

question 3
which is a lipid bound to a carbohydrate molecule?
glycolipid
d cholesterol
lipid bilayer
question 4
a membrane protein that completely spans the lipid bilayer is called a
lipoprotein
integral protein
intercellular space

Explanation:

For Question 3, a glycolipid is a lipid - carbohydrate conjugate. Cholesterol is a steroid lipid and a lipid bilayer is a double - layer of lipids. For Question 4, an integral protein completely spans the lipid bilayer. A glycoprotein has a carbohydrate attached and extracellular matrix is a network of macromolecules outside the cell.

Answer:

Question 3: glycolipid
Question 4: integral protein
