When measuring reaction velocity as a function of substrate concentration, a researcher usually keeps the concentration of enzyme at a constant level. What would happen if the enzyme concentration were not kept constant? A. Vmax would change, but Km would remain constant. B. Both Vmax and Km would change C. Vmax would remain constant, but Km would change D. Vmax would remain constant, but V would change E. None of the above would necessarily occur

WriteC if only statement A is correct, H if only statement B is correct, E if both statements are correct, M if both statements are incorrect. A. A competitive inhibitor would bind at the enzyme's active site.B. As a result, the affinity of the substrate to the active site decreases.
The representative reaction of the enzymatic process is:
A scientist is studying the enzyme X which is an important point of regulation in the metabolism of the inhabitants of Sumeru. He developed four Akademiyan-derived compounds which may possibly work against this enzyme, and tested using an eudiometer the metabolic rate of the sample cell lines. Data are below. Time for each compound (min) Eudiometer volume reading (mL) A B C D 0 83.1 62.6 89.0 66.4 5 83.2 100.6 90.2 71.4 10 83.2 83.6 95.0 77.2 15 83.2 83.6 100 84.6 20 83.3 110.8 104.6 88.2 Show the properly labeled volume versus time plot for each eudiometer, with the equation of the line and R2. What is the most effective inhibitor among the four compounds? It was found that the most effective inhibitor exhibits uncompetitive inhibition. Illustrate the Lineweaver-Burk plots of uninhibited and inhibited enzyme X with properly labeled axes.
Suppose we have 2 proteins A and B with the following kcat and Km values. kcat (s) Km (uM) Prot. A 5.4x10 Prot. B 6.8x10 4,000 50 Which enzyme is the more efficient one?

Tanzer-Gilbarg 2. most chemistry enzyme tests follow the zero order reaction where the sufficient amount of substrate is availbale the only limiting factor is the enzyme's substrate a. first statement is true and second statement is false b. both statements are true c. first statement is false and second statement is true d. both statements are true 3. any absorbance change per minute of activity when exceeds must be a. double the measurement and analyze again b. repeat analysis c. discared the reagent and open new one d. dilute sample and repeat analysis and multiply the dilution
When substrate concentration [S] << Km, the rate of an enzymatic reaction is increased by O increasing kcat/Km O increasing total enzyme concentration O increasing [S] O A and B O A, B and C
Which phrase characterizes a uncompetitive inhibitor? OA. binds either enzyme or enzyme-substrate complex when present, Km of an enzyme will appear to decrease OB. when present, Km of an enzyme will either increase or decrease when present, Km of an enzyme will appear to increase OD.
