Choose only the letter, no explanation needed. Enzyme activity is affected by a variety of factors. What factor causes the enzyme to denature if it becomes extremely high? * Choices: A. Water's Effect B. pH C. Temperature D. Activator's Effect An inhibitor binds to the enzyme's active site, preventing the substrate from binding to it. What conclusions can you make from this situation? * A. No reaction occurred B. Non-competitive inhibition occurred C. Enzyme activity occurred D. Competitive inhibition occurred Each enzyme is very selective when it comes to its substrate. What can you conclude from this statement? * A. Any substrate can bind to the active site. B. Enzymes are used up in the reaction. C. Only a specific substrate can bind to the active site. D. Enzymes break down when not used. Lock : Key :: Active Site : _____________________________ * A. Substrate B. Active Site C. Coenzyme D. Cofactor Enzymes only speed up biological functions, so they are NOT used up in the…
An inhibitor can decrease the number of ATP produced to 34 moles. Where does the inhibitor act? Name the enzyme that is in inhibited and the pathway with which it is usually associated.
As biological catalysts, enzymes play a fundamental role in many cellular processes. Which of the following statements about enzymes is correct? 1. Enzymes are essential for anabolic pathways; they are not required for catabolic pathways. 2. While an increase in temperature can increase the rate of an uncatalyzed reaction, it can’t increase the rate of an enzyme-catalyzed reaction. 3. Enzymes force substrates into unique conformations that do not occur in the absence of an enzyme. 4. Enzymes decrease the free energy of a reaction’s transition state. A. 1, 2 and 3 B. 1 and 3 C. 2 and 4 D. 4 only E. All of 1, 2, 3 and 4 are correct
What is the advantage of using ATP as a common energy source?Another way of asking this question is, “Why does ATP provide anadvantage over using a bunch of different food molecules?” For example,instead of just having a Na+/K+-ATPase in a cell, why not have manydifferent ion pumps, each driven by a different food molecule, like aNa+/K+-glucosase (a pump that uses glucose), a Na+/K+-sucrase (a pumpthat uses sucrose), a Na+/K+-fatty acidase (a pump that uses fatty acids),and so on?
The diagram shows the mechanism of a general enzyme‑catalyzed reaction. Put the labels in the correct locations. The abbreviations E, P and S indicate the enzyme, product, and substrate, respectively.
Draw a graph showing the change in free energy you would expect to see for the synthesis of ATP from ADP and PO4. Label DELTA - G , EA –enzyme, EA + enzyme
A common metabolic strategy is the lack of reactivity—that is, the slowness to react— of compounds whose breakdown is exergonic. For example, hydrolysis of ATP to ADP or adenosine monophosphate (AMP) is exergonic but does not take place without an appropriate enzyme present. Why would the cell use this metabolic strategy?
Quite often, medications cannot be taken with grapefruit juice. This is becausegrapefruit juice blocks an enzyme responsible for metabolism of the drug. Chemicals ingrapefruit juice bind to the active site of the enzyme. What type of inhibition is this, andwhat would it do to the amount of medication in your blood? Why is this bad for you explain?
