- Which of the following is not a mechanism that enzymes use to lower the activation energy of a reaction?arrow_forwardEnzymes work by lowering the activation energy needed to start biochemical reactions and increase the reaction rate. However, increasing the reaction temperature can also help to increase the reaction rate and speed up the reaction. In your opinion, does this mean all enzymes can be operated at an extreme reaction rate at an extremely high temperature?arrow_forwardEnzymes sometimes work as a key that opens the lock, if enzyme is the key then what is the physiological name of the molecule that could be the lock? Would the lock be Substrate?arrow_forward
- why does an enzyme not work well if its active site is changedarrow_forwardWould you expect an “enzyme” designed to bind to its target substrate astightly as it binds the reaction transition state to show a rate enhancementover the uncatalyzed reaction? In other words, would such a protein actuallybe a catalyst? Explain why or why not.arrow_forwardWhich one is transition and substrate state? What must be true of a and b in order for catalysis to occur?arrow_forward
- For a lot of enzymes that work on fatty acids, the rate determining step is the release of the product from the active site. This means that the activation energy for product release is much higher than the free energy of catalysis. What enthalpic or entropic contributions would make the activation energy for product release so high and explain?arrow_forwardin cells, an enzyme catalyzes the reaction ab → a + b. it was isolated, however, as an enzyme that carries out the opposite reaction a + b → ab. explain the paradox.arrow_forwardSuppose you have a fixed amount of the catalase enzyme. With this quantity, an experiment is made in which the concentration of the substrate increases. What will the graph of that reaction look like?arrow_forward
- the type of enzyme inhibition in which covalent bulky adduct prevents catalysis is ? a) uncompetitive b) reversible c) noncompetitive d) competitive e) Irreversiblearrow_forwardDraw a set of free energy diagrams that show the differences between a spontaneous reaction that proceeds quickly and a spontaneous reaction that occurs much more slowly. How would an enzyme affect the way you draw these free energy diagrams?arrow_forwardWhat general kinds of reactions do the following types of enzymes catalyze?(a) Kinases (b) Isomerases(c) Synthetasesarrow_forward
