- What is the CORRECT sequence of events to activate an enzyme? Group of answer choices a. enzyme/product complex-enzyme/substrate complex-products leaving active site-substrate entering active site b. enzyme/product complex-products leaving active site-enzyme/substrate complex-substrate entering active site c. substrate entering active site- enzyme/product complex-enzyme/substrate complex-products leaving active site d. substrate entering active site-enzyme/substrate complex-enzyme/product complex-products leaving active siteDefine the following terms:a. catalystb. transition statec. substrated. activation energye. active site2. Define the follthe amino acid glutamic acid is at the active site of an enzyme. Normally the enzyme is active at pH 7. at pH 4 (higher concentration of H+), the enzyme is inactive. Explain there observations
- Identification of the active site of an enzyme: 2.2 The use of substrate analogues summaryIdentify the type of enzyme inhibition each of the following inhibitor characteristics is associated with: 1. An inhibitor that decreases enzyme activity by binding to a site on the enzyme other that the active site. 2. An inhibitor that inactivates enzymes by forming a strong covalent bond of the enzyme acitve site.Compare Lock&key and Induced fit mechanism of enzyme action.
- The active site of an enzyme ___. is where the coenzyme is located is a specific bulge or protuberance on an enzyme is a groove or crevice in the structure of the enzyme complementary to the substrate will react with only one substrate no matter how many molecules may resemble the shape of the substrate rigidly resists any alteration of its shapeDraw an enzyme that has two substrates, include these substrates. Make sure that the substrate binding site is included in your drawing. Add to your drawing by depicting the same enzyme, but with product instead of substrate. Link your two drawing by adding arrow(s) to show their relationships.Classify the items as competitive or noncompetitive inhibitors for control of enzyme action. Bind to the allosteric site on the enzyme Not influenced by the concentration of substrate Resemble the substrate Do not resemble thhe substrate Bind to active site of the enzyme
- The apo form of an enzyme: (select all that applies) Group of answer choices Is the cofactor-free form Is the cofactor-bound form often exhibits impaired catalytic activity concerns only metal ions cofactorsAn Eadie-Hofstee plot is shown below for the different types of enzyme inhibition. Match the line withthe type of inhibition.(a) Line A Inhibition Mechanism. Ans: ________(b) Line B Inhibition Mechanism. Ans: ________(c) Line C Inhibition Mechanism. Ans: ________An inhibitor was added to an enzyme and the expected rate of the reaction was not detected and the substrate was not utilized at all. This inhibitor is (choose one answer only): Is un-competitive, meaning the inhibitor binds to a site near the active site. Is competitive, meaning the inhibitor binds directly to the same active site as the subtrate. Is non-competitive, meaning the inhibitor binds to site other than the active site as the subtrate. Is irreversible, meaning the inhibitor binds covalently to the enzyme keeping the enzyme inactive permanently.
