Which of the following statements is NOT true? None of the other four answers (all are true) The energy required to cause a chemical reaction to occur is called the activation energy Decomposition (degradation, catabolic) reactions are usually endergonic Chemical reactions in living cells are catalyzed by enzymes Enzymes increase the probability that a chemical reaction will take place by lowering the activation energy
When the enzyme hexokinase binds to glucose and ATP it undergoes a conformational change. All of the following are true about this enzyme-substrate binding EXCEPT: The active site changes shape so that it binds more tightly to the substrates The substrates are optimally positioned for the reaction to occur The substrates become contorted or strained, which increases their reactivity The activation energy of the reaction increases
An allosteric inhibitor does which of the following? a. Binds to an enzyme away from the active site and changes the conformation of the active site, increasing its affinity for substrate binding. b. Binds to the active site and blocks it from binding substrate. c. Binds to an enzyme away from the active site and changes the conformation of the active site, decreasing its affinity for the substrate. d. Binds directly to the active site and mimics the substrate.
Which statement is true? A person obtains all of the body's coenzymes from their food.. Enzymes are specific in their catalytic function. Enzymes decrease the rate of a chemical reaction. All enzymes need to have chemical cofactors to function properly.
In competitive inhibition, increasing concentrations of the inhibitor will have the following effect on the kinetics of the enzyme: A. Km will decrease. B. Vmax will stay the same. C. The reaction will cease because the inhibitor binds irreversibly. D. Km / Vmax will stay the same.
Which of the following is NOT true about enzymes? Enzymes are proteins Enzymes raise the activation energy of a chemical reaction Enzymes help a chemical reaction to occur more quickly Enzymes have an active site Enzymes may be controlled by feedback inhibition
Enzymes are specific, they match with a specific and particular reactant during the reactions, the enzyme changes shape and cannot be used again true or false
Enzymes are not used up in chemical reactions, so what exactly does an enzyme do? Refer to activation energy (transition state etc)
What are the steps for an enzyme to create a product in order: The energy of activation is lowered so the reaction can happen quicker. Substrate attaches to the active site. The product is created and released from the active site. The energy of activation is lowered so the reaction can happen slower. A specific substrate attaches to the active site.
