14. A functional enzyme together with its cofactors is called:A. Holoenzyme15. With regards to the Michaelis-Menten equation, a molecule that has the effect of increasing the Vmax of a reaction upon binding to an enzyme would be called what?A. Activator16. Which statement is true of enzymes?B. The activity of an enzyme might change as pH changes.17. What is true of an uncompetitive inhibitor?A. It binds only to the complex formed between the enzyme and the substrate.18. What is true of a competitive inhibitor?A. It has a structure similar to the substrate.19. How would a fever most likely affect the activity of enzymes in human body?B. It could slow or stop enzyme function.20. What will happen with the amount of the enzyme after biochemical reaction:B. The amount of the enzyme will never reduce21. The Michaelis-Menten equation is a mathematical model that describes the rate of an enzyme-catalyzed reaction as a function of the concentration of the substrate. The equation is given by:V = (Vmax * [S]) / (Km + [S])Where:V is the initial velocity of the reactionVmax is the maximum velocity of the reaction[S] is the concentration of the substrateKm is the Michaelis constant, which is the substrate concentration at which the reaction velocity is half of Vmax.The Michaelis-Menten equation is used to determine the kinetic parameters of an enzyme, such as Vmax and Km, which provide information about the enzyme's catalytic efficiency and substrate affinity, respectively.
