Animals are not able to convert fatty acids into carbohydrates. The net synthesis of 1 mol of oxaloacetate from 2 mol of acetyl‑CoA by the citric acid cycle does not occur because 1 mol of oxaloacetate is used in the cycle for each one generated. Plants are able to convert 2 mol of acetyl‑CoA into 1 mol of oxaloacetate with only two additional enzymes not found in animals. This process is called the glyoxylate cycle, and it occurs in organelles called glyoxysomes. Identify the enzyme in each step of the glyoxylate cycle. Not all the enzyme names will be used.

Modern pennies are composed of zinc coated with copper. a student determines the mass of a penny to be 2.482 g and then makes several scratches in the copper coaling (to expose the underlying zinc). the student puts the scratched penny in hydrochloric acid, where the following reaction occurs between the zinc and the hcl (the copper remains undissolved): zn(s) + 2 hcl(aq) → h2(g) + zncl(aq)the student collects the hydrogen produced over water at 25 °c. the collected gas occupies a volume of 0.899 l at a total pressure of 79 j mmhg. calculate the percent zinc (by mass) in the penny. (assume that all the zn in the penny dissolves.)

If a molecule with a molecular formula of c13h18 is treated with an excess of h2 in the presence of finally divided pt metal under conditions required for maximum hydrogenation of the molecule to give a molecule with a formula c13h24, how many rings are in the molecule?
