Lipids: For each statement below, write in the blank (A) if it applies to triacylglycerols; (B) if it applies to phospholipids; (C) if it applies to glycolipids; (D) if it applies to steroids. There is only one "best" answer per blank: cholesterol is the most common lipid in this category. Complex four-ring structures found only in animal cell membranes. Glycerol + 3 fatty acids are in this category. Lipid-based hormones (estrogen, progesterone) are in this category. Major constituent of the lipid bilayer of cell membranes. Provides chemical energy from stored supplies. Phosphate substitution for fatty acid on triacylglycerol. Results from storage lipid. Stored in adipose cells of a fatty acid on a triacylglycerol. Sugar (carbohydrate) substitution. Vitamin D is a derivative.

Which of the following is not a way to associate membrane proteins with the lipid bilayer? Group of answer choices: a. Hydrophobic amino acids that form a short domain in membrane proteins are in contact with the lipid bilayer. b. Proteins are attached to the lipid bilayer on its surface via covalently linked to one or more lipid groups. c. A protein can be bound to the lipid bilayer by interacting with other membrane proteins. d. A protein can be embedded into the lipid bilayer by forming hydrogen bonds between amino acid side chains and phospholipids. Na+-K+ pump is Group of answer choices: a. one kind of ion channels b. an active carrier protein c. an antiporter d. b and c

A common structural feature of membrane lipids is their amphipathic nature. For example, in phosphatidylcholine, the two fatty acid chains are hydrophobic and the phosphocholine head group is hydrophilic. For each of the following membrane lipids, name the components that serve as the hydrophobic and hydrophilic units: (a) phosphatidylethanolamine; (b) sphingomyelin; (c) galactosylcerebroside; (d) ganglioside; (e) cholesterol.
