2. Consider the following portion of the glycolytic pathway catalysed by the enzymes (E1- E6) above...
QUESTION 7 Consider the biochemical pathway A+E1 --> B+E2 --> C, where A, B, and Care substrates and products and E1 and E2 are the enzymes that catalyze the reactions. Enzyme 1 (E1) can utilize only B as substrate. O only A as substrate. both A and B as substrates either A or B as substrate, but not both. neither A nor B as substrate.
For letters h & i : For each of the following reactions, predict the major mechanistic pathway (SN1/SN2/E1/E2) and the major organic products 1. (cont.) (h) НСОН CHB -CHBr HCOH - (0) CH,CH,CH,CH,Br- NH 2. For each of the following indicate which reaction will occur faster. Explain your reasoning. (No credit will be given for guesses) (a) The reaction of (CH),CBr with 0.001M aqueous NaOH or 0.10M aqueous NaOH (b) The reaction of 2-bromobutane with NaOH in DMSO or NaSH...
