Which of the following is TRUE of reactions that follow Michaelis-Menten kinetics? At both low and high substrate concentrations, rate is only dependent on total enzyme concentration. At high substrate concentrations, rate is only dependent on total enzyme concentration. At low concentrations of substrate, rate is only dependent on Vmax At both low and high substrate concentrations, rate is only dependent on substrate concentration. At low concentrations of substrate, rate is only dependent on kcat.

4. Basic concepts of Michaelis-Menten kinetics. The Michaelis-Menten equation is expression of the relationship between the initial velocity, Vo, of an enzymatic reaction and substrate concentration, [S]. There are three conditions that are useful for simplifying the Michaelis-Menten equation: [S] <<Km; [S] = Km; [S] >> Km. Match each condition with the statement(s) that describe it. TV, Vmox[S] Vo =Vmax m . V Vo - Vmax [S] Km +[S] V. (um/min) max [S] (mm) (a) Doubling [S] will almost double...

Q1. WHAT ARE ENZYMES? HOW DOES ENZYME-SUBSTRATE BINDING TAKES PLACE? Q2. IN MICHAELIS -MENTEN GRAPH, WHY DOES THE CURVE REACHES PLATEAU? Vmax Reaction velocity (v) Vm/2 Km Substrate concentration (S) Q3. IN MICHAELIS MENTEN GRAPH, HOW WOULD YOU INCREASE VELOCITY BEYOND Vmax? Q4. SMALLER VALUE OF THE MICHAELIS CONSTANT (Km) REFLECTS HIGHER EFFICIENCY OF THE ENZYME. (TRUE/FALSE).
