Here is a metabolic pathway in which precursor A is converted into the final product D. The sequence of steps in this process is as follows: Enzyme 1 Enzyme 2 Enzyme 3 Precursor A ? B ? C ? D Each of the enzymes shown is the product of a different gene. Part A Which of the metabolite(s) would be missing in cells that are mutant for enzyme 2? Select all that apply. A B C D

Step 1
If enzyme 2 is mutated, it means that the conversion from the product of enzyme 1 to the substrate for enzyme 3 cannot occur. Show more…

A hypothetical three-step metabolic pathway consists of the intermediates W, X, Y, and Z, and the enzymes that catalyze the reactions A, B, and C. Determine the order of the metabolic pathway and the enzymes that catalyze the reactions based on the following information: 1) An inhibitor of enzyme B causes Z to build up. 2) An organism with a mutation in enzyme C requires Y to grow. 3) An inhibitor of enzyme A causes W, Y, and Z to build up. 4) An inhibitor of enzyme C causes W and Z to build up. You MUST provide your answers using capital letters and place the enzymes that catalyze each reaction in between the intermediates (e.g. WAXBYCZ would be the answer if the pathway was W -> X -> Y -> Z and the enzymes A, B, and C catalyze the first, second, and third reactions respectively). Do NOT include spaces!

In regards to enzymatic pathways, what is an intermediate? a.The product of an enzymatic reaction that is also the substrate for another enzymatic reaction. b.The enzyme that catalyzes the next reaction in a series. c.The product of an enzymatic reaction that is defective, and therefore secreted from the cell. A product that can help a bacteria complete a metabolic pathway.

enzyme 1 enzyme 2 A B C Examine the simple metabolic pathway in the figure above. If A, B, and C are all substances required for growth of the organism that carries out this pathway, a strain that is mutant for the gene encoding enzyme 1 would be able to grow on which of the following media? minimal medium minimal medium supplemented with nutrient B only minimal medium with no supplements minimal medium supplemented with nutrient A only
