The zero order rate is seen in an enzyme catalyzed reaction when:
A. There is too much enzyme and too little substrate
B. Enzyme reactions are always first order
C. The Michaelis constant is very high
D. The Vmax of the reaction is twice that which is observed
E. The enzyme substrate comples is at its maximum concentration
What happens when you add more enzyme to a catalyzed reaction that already is proceeding at Vmax?
A. The reaction is inhibited because of competition for substrate
B. The plot of velocity vs. [S] will show a sigmoidal (an S-curve) shape
C. The reaction goes faster
D. The Km of the reaction will change
E. There is no change in the rate of the reaction
Given two enzymes with the same Vmax but with very different Km values
A. The enzyme with the higher Km will approach Vmax at smaller [S]
B. Vmax values cannot be the same with different Km values
C. The steady state concentration of the enzyme-substrate complex is the same for each enzyme at every substrate concentration
D. The enzyme with a lower Km value approaches Vmax at lower [S]
E. Both values change when more enzyme is sdded
I think first one is E, second one is E, and last one is C. What are the correct answers for above?
