Which of the following is NOT a true statement about the diagram below? Intermediate A Pathway operates Intermediate B End-product Pon O O O O Substrate -Enzyme 1- Allosteric ste -Enzyme 2 Enzyme 3 Pathway shuts down Bound end-product .. The diagram shows a metabolic pathway Each enzyme is specific for its substrate The product of each enzyme reaction becomes a substrate for the next enzyme None of the other four answers (all are true statements) The end-product serves as a competitive inhibitor of the substrate on Enzyme 1

Many enzymes help in cellular respiration. Using the figure to the right, explain the difference between this reaction with and without an enzyme. You must use the following terms in your answer; active site, induced fit, substrate and activation 1. Enzyme Action Without enzyme Activation energy without enzyme energy. With enzyme Activation energy with enzyme Reactants: Glucose + 0, Overall energy released during reaction Products: co, + H,0 Do NOT answer both questions 2 and 3. Choose only ONE to answer in the space provided. 2. The enzyme catalase is a polypeptide. Would you expect this enzyme to move through the cell membrane via simple diffusion? Explain your answer and provide a possible solution if catalase can't move across a membrane. 3. It is important for humans to make sure they consume small amounts of minerals (e.g. magnesium oxide or zinc oxide) in their food or in a supplement of some sort. Explain the value that some minerals play in assisting with many of our body's…

What are the steps for an enzyme to create a product in order:  The energy of activation is lowered so the reaction can happen quicker. Substrate attaches to the active site. The product is created and released from the active site. The energy of activation is lowered so the reaction can happen slower. A specific substrate attaches to the active site.
