Structure of Product B and name of Enzyme 2.   etc.

Given the active site diagram below, identify the mechanism(s) of catalysis. 2 1 5 Metal ion Induced Fit Acid-base S Acid-base, Metal ion By Approximation -3 4

The Ki for a competitive inhibitor pyrrole-2-carboxylate is 0.05M.Calculate the initial velocity if the substrate concentration is 0.25M and 1.0 mole/liter of the inhibitor is added to thereaction.

Under standard conditions, will the following reaction proceed spontaneously as written?

How does the rate of the forward reaction compare to the rate of the reverse reaction for an endergonic reaction? For an exergonic reaction? Explain.

Complete the balanced equation for the overall reaction by selecting an answer choice in the brackets.  Sucrose + [2 Pi, 4Pi]+[4 ADP, 2 ADP, 4 ATP, 2ATP]+[2 NAD+, 4 NAD+, 6 NAD+]+[H2O, 5 H2O, 3 H2O] --> [2 cirate, 2 oxaloacetate, 2 pyruvate, 2 acetyl-coA]+[4 ADP, 2 ADP, 4 ATP, 2ATP] + [2 NAD+, 4 NAD+, 6 NAD+] + [2H+, 8H+, 6 H+, 4 H+, 10 H+]     Does the commercial process require aerated culture medium—that is, is this a fermentation or an aerobic process? A. a fermentation process, because A. niger cells must use O2O2 to continuously regenerate NAD+ B. an aerobic process, because A. niger cells must use O2O2 to continuously regenerate NAD+ C. a fermentation process, because A. niger cells cannot use O2O2 to continuously regenerate NAD+ D. an aerobic process, because A. niger cells cannot use O2O2 to continuously regenerate NAD+
