2 3.) (22) a.) Phosphorylated sugars are less likely to exit the lipid bilayer True False than non-phosphorylated sugars. b.) Channels tend to transport ligands faster than pumps. True False c.) Phospholipids and glycolipids can form micelles. True False d.) Saturated fatty acids have higher melting points than unsaturated True False fatty acids of the same length. e.) The β -2-deoxy-D-ribose follows the general formula: [C(H 2 O)] n True False f.) ATP has the highest phosphoryl transfer potential of all biomolecules. True False g.)
