HK 100 EXAM 2 FINAL PAPER TEST BANK
WITH VERIFIED QUESTIONS AND
DETAILED SOLUTIONS
●● Michaelis-Menten equation
Answer: V = (Vmax[S]) / (Km + [S])
●● Km definition
Answer: Substrate concentration at 1/2 Vmax
●● Km meaning
Answer: Inversely related to enzyme affinity (low Km high affinity)
●● Vmax definition
Answer: Maximum velocity when enzyme is saturated
●● At substrate equals Km
Answer: Reaction rate is 1/2 Vmax
●● Lineweaver-Burk equation
Answer: 1/V = (Km/Vmax)(1/[S]) + 1/Vmax
, ●● Lineweaver-Burk y intercept
Answer: 1/Vmax
●● Lineweaver-Burk x intercept
Answer: -1/Km
●● Lineweaver-Burk slope
Answer: Km/Vmax
●● Competitive inhibition
Answer: Inhibitor binds active site increases Km does not change Vmax
●● Noncompetitive inhibition
Answer: Inhibitor binds away from active site decreases Vmax does not
change Km
●● Irreversible inhibition
Answer: Covalent binding permanently inactivates enzyme
●● Competitive inhibition effect at high substrate
Answer: Can be overcome by increasing substrate concentration
