what is Km - ANSWER-concentration of substrate at 1/2 Vmax what is Km inversely related to - ANSWER-the affinity of the enzyme for its substrate (low Km=high affinity & high Km=low affinity) what is Vmax directly proportional to - ANSWER-enzyme concentration most enzymes follow what kind of kinetics - ANSWER-Michaelis-Menten kinetics (line up and then it flattens out, hyperbolic) if an enzymatic rxn shows a sigmoid curve what does that indicate - ANSWERcooperative kinetics (hemoglobin) do...

Define Km in MM kinetics: - ANSWER-The concentration of substrate [S] at which 1/2 Vmax is reached Km is _________ related to affinity of the enzyme for its substrate - ANSWER-inversely Vmax is directly proportional to what? - ANSWER-to the enzyme concentration What characterizes MM kinetics? - ANSWER-a hyperbolic curve when Vmax is plotted against [S]. Most enzymes follow MM kinetics. Enzymatic reactions demonstrated a sigmoid curve usually denote: - ANSWERcooperative binding / kinetics, ...

BCH 361 Ch. 7 TEST QUESTIONS WITH CORRECT ANSWERS Match the condition w/ the statement that describe it. This condition will result in the highest rate. A. [S]= 10Km B. [S]= Km C. [S]= 0.1Km - Answer-A Match the condition w/ the statement that describe it. Doubling [S] will have little effect on the rate. A. [S]= 10Km B. [S]= Km C. [S]= 0.1Km - Answer-A Match the condition w/ the statement that describe it. About 90% of the active sites are occupies by substrate A. [S]= 10Km B. [...

BCH 369 CHAPTER 7 TEST QUESTIONS WITH ANSWERS ALL REVISED AND UPDATED Michaelis-Menten equation - Answer-A mathematical expression that describes the activity of an enzyme in terms of the substrate concentration ([S]), the enzyme's maximal velocity (Vmax), and its michaelis constant (Km): Vo = Vmax [S]/(Km + [S]). catalytic constant (Kcat) - Answer-The ratio of the maximal velocity (Vmax) of an enzyme-catalyzed reaction to the enzyme concentration. Also called a turnover number. Turnover...
