Induced fit means that when a substrate binds to an enzymes active site, (a) it fits perfectly, like a key in a lock (b) the substrate and enzyme undergo conformational changes (c) a site other than the active site undergoes a conformational change (d) the substrate and the enzyme become irreversibly bound to each other (e) c and darrow_forward8).

(2) Temperature and pH have no effect on the action of this enzyme. (3) This enzyme works best at a temperature above 50°C and a pH above 12. (4) This enzyme works best at a temperature of 35°C and a pH of 8. Relative Rate of Enzyme Action Relative Rate of Enzyme Actionarrow_forward
- A dichotomous key works by determining positive and negative reactions to different biochemicals. Why does this method allow us to identify one species of organism from another? – for this question, do not describe the dichotomous key procedure, think about why it works, what are biochemical reactions based on? Think enzymatic pathways, what are enzymes, what are they a reflection of? Keep the answer between 2-3 sentencesarrow_forwardCongratulations! You have just secured a great job in a pharmaceutical company. You are doing an experiment in which you are measuring the rate at which succinic acid is converted to fumaric acid by an enzyme succinic dehydrogenase because you want to design a drug that can block this step in the metabolic pathway of a pathogenic bacteria. You decide to add a little malonic acid to make things interesting.. You observe that the reaction rate slows markedly and being a very smart graduate of Medgar Evers College, you conclude that malonic acid must be acting as an inhibitor. Design an experiment that will help you decide if malonic acid is acting as a competitive inhibitor or a noncompetitive inhibitor. Go to work and expect a promotion. Good luck.arrow_forwardWhich is most likely to be tightly bound by an enzyme? a)Analog of the starting material (SM), because the SM is tightly bound to start the reaction b)Analog of the transition state (TS), because binding TS tightly catalyzes the reaction c)Analog of the product (P), because binding the P tightly makes the reaction more downhill d)All of the above are approximately equally truearrow_forward
- 1. Carols first question was, “What is an enzyme” a. Use the enzyme lactase as an example, and explain how it functions(figure 4.1) b. What is the substrate for lactase. c. What are the end products of this reaction?arrow_forward5. Enzymes are incredibly effective at facilitating chemical reactions and must be controlled- or the chemical reaction won't stop and the reactant(s) might be used up. (A) Use 3 different colors to color the coding circles and corresponding structures in the figures. (B) Draw an arrow pointing to the active site in each figure. (C) Beneath each diagram, write the type of inhibition and briefly, in your own words, explain what is happening.
