- Part A: Say that a cell is running a metabolic pathway that follows the same pattern as the diagram and something happens that prevents enzyme 3 from reacting normally. Of the following options, which one is the end result of this interrupted metabolic pathway? Part B: for this reaction to be an example of feedback inhibition, the ____ would have to be blocking enzyme 3. Answer choices: • pH • Product • Salinityarrow_forwardWhat is the key activity of Panel II in the figure above? The enzyme is consumed as the products form. The substrate leaves the active site. The conversion of substrates to products occurs. The product leaves the enzyme. The product decomposes to the reactants.arrow_forwardWhen an enzyme interacts with the substrate, which of the following occurs? Question 9 options: The protein frees a substrate so that it can cause a chemical reaction within the cell. The protein and substrate adjust their shape slightly during binding to facilitate catalysis. The substrate unlocks a protein within the cell so that it can cause a chemical reaction. The tertiary structure of the protein and the shape of the substrate are identical.arrow_forward
