Students have asked these similar questions

The graph shows the reaction coordinate of an enzymatic reaction of substrate to product a) which number correlates with the overall Keq of the reaction going from S to P? b) which number correlates with the velocity of the reaction WITHOUT enzyme (ie. starting with only substrate)? C) which number correlates with the overall velocity of the reaction WITH SATURATED enzyme D) the initial velocity of this reaction increases by a specific factor in the presence of enzyme. The difference between which two numbers best correlates with this enhancement in velocity? 1) 3 and 1 2) 3and 2 3) 3 and 4 4) 3 and 5 5) 3 and 6

For the reaction A ==> B, Delta G'° = -60 kJ/mol. The reaction is started with 10 mmol of A; no B is initially present. After 24 hours, analysis reveals the presence of 2 mmol of B, 8 mmol of A. Which is the most likely explanation? OA) A and B have reached equilibrium concentrations B) An enzyme has shifted the equilibrium toward A C) B formation is kinetically slow; equilibrium has not been reached by 24 hours ○ D) Formation of B is thermodynamically unfavorable ○ The result described is impossible, given that Delta G'o is -60 kJ/mol

Most enzymes have optimum operating conditions to function at maximum rate or velocity. Some of these conditions are the pH temperature the enzyme concentration and the substrate concentration. The optimum pH and temperature values for most enzymes are: a) pH of 1.0 and + 100 oC b) pH of 11.0 and - 7 oC c) pH of 7.0 and + 37 oC d) pH of 14.0 and + 370 oC e) None of the above
