Which of the following statements is false regarding an enzyme's ability to catalyse a reaction? an enzyme provides a reaction surface and a hydrophilic environment for the reaction to take place an enzyme binds reactants such that they are positioned correctly and can attain their transition-state configurations an enzyme allows the reaction to go through a more stable transition state than would normally be the case an enzyme can weaken bonds in reactants through the binding process
Background: In this experiment, the lab instructor created a catecholase enzyme solution using white potatoes. The potato was the source of enzymes and cofactors in the experiment, as potatoes have sufficient amounts of catecholase and, therefore, cofactors for catecholase. A chilled potato had the peel removed by the instructor and then was chopped into pieces. The potato is peeled so that the brown skin does not interfere with the brown color of the benzoquinone. If this were to occur, the absorbance would seem higher due to the brown potato skin in the solution. The potato was chopped so that the blender did not need to work as hard to break open the cells. The instructor then placed the chopped, peeled potato into a chilled blender. The blender is chilled as heat will speed up the rate of reaction. Cold (chilled) distilled water was then added to the potatoes. This was done to break open the cells of the potato. The catecholase and cofactors are inside the potato cells; water is…
Consider the following free energy diagram for an uncatalyzed and enzyme-catalyzed reaction. Select all the statements that are true. Without enzyme With enzyme A+B Time AB Oa. The reaction is now spontaneous due to the addition of enzyme b. The rate of the enzyme catalyzed reaction is faster than the uncatalyzed reaction O C. The reaction is exergonic O d. The change in free energy for the reaction is greater in the catalyzed reaction, compared to the uncatalyzed reaction e. The enzyme stabilizes the transition state for the reaction Released Energy pes
You are observing an enzyme driven reaction. To the reaction mixture you add a chemical X which inhibits the reaction. If you add more substrate, the reaction rate approaches the Vmax of the uninhibited reaction. Furthermore, the structure of X is similar to the natural substrate. What kind of inhibitor is X?
Which of the following are characteristics of catabolic metabolic pathways? (Choose all correct answers). Overall oxidation of initial substrates so redox reactions involve use of NAD+ as oxidizing agent, converted to NADH. Large initial substrates are broken down to smaller final products. Overall reduction of intial substrates so redox reactions involve use of NADPH as reducing agent, converted to NADP+. The pathways are overall exergonic (negative delta G). Net production of ATP as a result of the pathway. Essentially irreversible
