Select all answers that apply. Which of the following are common features of phospholipids and triacylglycerol? They are both present in the membrane They both have a glycerol backbone They both contain fatty acids They are both amphipathic They are both synthesized via hydrolysis reactions

Which one of the following is a "high-energy" biomolecule with a more negative AG° value for hydrolysis than ATP? 1,3-Bisphosphoglycerate Fructose-1,6-Bisphosphate Dihydroxyacetone Phosphate Glucose-6-Phosphate Glycerol-1-Phosphate O0000

In a fatty acid, the shorter the carbon chain, the more solid the fatty acid becomes. True False

The figure below illustrates the molecular structures of two fatty acids. A B H₂C The structural formula of erucic acid and behenic acid с H₂C D erucic acid behenic acid Which of the following best explains why erucic acid is liquid at room temperature but behenic acid is solid at room temperature? O OH The presence of a double carbon to carbon bond in erucic acid prevents the molecule from packing closely together. The lack of any double carbon-carbon bonds in behenic acid causes the molecule to be come polar and therefore packed more tightly. The larger number of carbon atoms in erucic acid prevents the molecule from packing tightly together. OH The smaller number of carbon atoms in behenic acid creates stronger covalent bonds between the carbon atoms allowing for them to pack more tightly together.
