Question 2 (0.5 points) Humans store energy in the form of glycerol, triacylglycerols, and fatty acids. None of these. Question 3 (0.5 points) Which of the following statements is true? Triacylglycerols can be hydrolyzed with water to form glycerides and fatty acids. Glycerides can be hydrolyzed with water to form triacylglycerols and fatty acids. Triacylglycerols can be hydrolyzed with water to form glycerol and fatty acids. None of these statements is true. Question 4 (0.5 points) What are unsaturated fatty acids? Unsaturated fatty acids have no double bonds in their long hydrocarbon chains. Unsaturated fatty acids have one or more C=O bonds in their long hydrocarbon chains. Unsaturated fatty acids have one or more C=C bonds in their long hydrocarbon chains. Unsaturated fatty acids are all solid at room temperature.

Why is the following molecule nonpolar and hydrophobic? (3 points) The carbon and hydrogen atoms share electrons equally. The glycerol molecule in fats contains a carboxyl group. There are exactly three fatty acid chains present in each fat molecule. There is an unequal distribution of hydrogen and oxygen atoms. 5. (01.03 LC) A common feature of starch and glycogen is that molecules of both (3 points) are important structural components of plant cell walls. contain repeated monomers of glucose and galactose. form microfibrils that give support to connective tissue fibers. store energy for use by living organisms.
