- Select all the statements that are correct with respect to enzymes: Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation. SHOW MORE V During an enzymatic reaction - the enzymes are not used up in the reaction and actually they can be recycled as long at a the reactant is available b The special molecules that catalyze biochemical reactions are called enzymes. they perform the critical task of lowering the activation energies of chemical reactions inside the cell. d they perform the critical task of increasing the activation energies of chemical reactions inside the cell. e enzymes don't change whether a reaction is exergonic (spontaneous) or endergonic. f The chemical reactants to which an enzyme binds are the enzyme's active site The chemical reactants to which an enzyme binds are the enzyme's substrates h The location within the enzyme where the substrate binds is called the enzyme's active site.Characterization of enzyme activity does not allow us to: a. determine how different variables affect the enzyme's ability to function b. determine the molecular composition of the enzyme c. determine the optimal environment for an enzyme to function d. determine the effect of inhibitors on the enzymeWhich of the following statements are false? Initial velocities of enzyme reactions are best obtained in the absence of product because it simplifies analysis. Initial velocities refer to the velocity of the reaction right after it is initiated. The velocity of the reaction as a function of measuring time are curved just like an isothermal binding curve because of substrate binding to the enzyme. Initial velocities correspond to the pre-steady state condition for free enzyme. Initial velocities can sometimes be measured by spectroscopy such as UV/Vis spectroscopy when monitoring the production of NADH from NAD+. The velocity of the reaction will eventually go to zero. The reaction will reach equilibrium because of the presence of the enzyme. It is always better to use substrate rather than product to measure enzyme kinetics.
- Other than temperature and PH, discuss, in detail. Additional factors often necessary for the proper function of many enzymes in biological systems.Please handraw this graph with all the necessary detailed information: Imagine that I text enzyme rate for four different temperatures: 10 degrees celsius, 20 degrees celsisus, 30 degree celsius, and 40 degree celsius, in separate tubes. The enzyme appears to work faster as temperature increases, but completely ceases activity at 40 degrees celcius. Sketch a graph to show this outcome, but here you will graph product formation (nmoles/mL) vs. time (minutes). The graph should be 4 lines and HANDDRAWN. Include a legend if necessary. You do not need precise quantitivate values, but most show the correct trends on the graph.The figure displays the relationship between initial rate of product formation and reactant concentration in an enzyme-catalyzed reaction with a fixed amount of enzyme. Which of the following statements best explains the shape of the rate curve at high reactant concentration?
- Regarding the physical condition (characteristics of the solution/environment) in which an enzyme finds itself: sometimes enzymes are most active at a certain level and still active but to a lesser degree at a level above or below the optimal level. Describe the likely reason for the enzyme’s decrement in function at levels other than the optimal level?An enzyme has a single active site at which it can bind and hydrolyze either X or Y but the enzyme cannot bind X and Y at the same time. Which of the following statements are TRUE? Multiple answers: Multiple answers are accepted for this question Select one or more answers and submit. For keyboard navigation. SHOW MORE The Km for X will be affected if Y is present in the reaction mixture. a Y is a competitive inhibitor of X. The Km for X will increase. d The Vmax for X will be affected if Y is present in the reaction mixture. pH dependence of Vmax reflects the ionization state of catalytic site residues. e Consider the following: X and Y are methanol (poisonous) and ethanol respectively. If the Km for X= 0.01 M and the Km f for Y = 0.001 M then 0.01 M Y is 10 times the concentration of Y required for 0.5 Vmax. Addition of an enzyme to a chemical reaction increases the ratio of products to reactants (Ken). A mutation in the active site of an enzyme resulting in a large increase in…An inhibitor was added to an enzyme and the expected rate of the reaction was not detected and the substrate was not utilized at all. This inhibitor is (choose one answer only): Is un-competitive, meaning the inhibitor binds to a site near the active site. Is competitive, meaning the inhibitor binds directly to the same active site as the subtrate. Is non-competitive, meaning the inhibitor binds to site other than the active site as the subtrate. Is irreversible, meaning the inhibitor binds covalently to the enzyme keeping the enzyme inactive permanently.
