- Draw 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.A very special property of enzymes is Feedback inhibition. What is feedback inhibition? Draw a hypothetical cyclic pathway where in there are 7 reactions to show feedback inhibition.We can increase the rate of a reaction by decreasing the activation energy. And, we can do it by using an enzyme. Explain how enzyme decrease the activation energy.
- What is true about a competitive inhibitor of an enzyme? You can choose more than one a. it binds the active site b. it binds an allosteric site c. it physically blocks the substrate d. it warps the active site e. it can be overcome with large amounts of substrateWhat is the item labeled "B" in the above figure? The enzyme The substrate The active site The transition state The productYou are observing an enzyme driven reaction. To the reaction mixture you add a chemical X which inhibits the reaction. If you add more substrate, the reaction rate approaches the Vmax of the uninhibited reaction. Furthermore, the structure of X is similar to the natural substrate. What kind of inhibitor is X?
- The region of an enzyme to which a substrate binds is called the ______ site. active substrate enzymatic conformationalChoose 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…The active site of an enzyme binds specifically to a substrate. Your text mentions an early idea which is that this enzyme-to-substrate interaction is like a lock and key, but it then describes a more accurate model for how enzymes bind to their substrates. Explain why the interaction is not like a lock and key and more like a hand grasping a doorknob. What is the specific name of the 'model' of how enzymes bind to their substrates?
- "An enzyme reaches a maximum rate at high substrate concentration because it has a fixed number of active sites where substrate binds", is true or false.Let's imagine I want to construct a competitive inhibitor for an enzyme one day. Should it be similar to the transition state, similar to the substrate, similar to the product, or form a covalent link with the enzyme?In competitive inhibition, can both the inhibitor and the substrate bind to an enzyme at the same time? Explain your reasoning
