- which of the following is a primary function of the active site of an enzyme?arrow_forwardTwo substrates (A and B) are used to produce a certain biological product in an enzyme- catalyzed reaction. It is found that both substrates must bind to the enzyme, first Substrate A, then Substrate B before the product is produced. What kind of kinetic mechanism is described? Linear Reaction Ordered Sequential Reaction Random Sequential Reaction Ping Pong Reactionarrow_forwardAn inactive form of an enzyme becomes active after being phosphorylated. When glucose is converted to glucose-6-phosphate by hexokinase, the accumulation of glucose-6-phosphate inhibits the reaction. A foreign substance is added to the reaction above. This substance binds to hexokinase and prevents its ability to catalyze the reaction.arrow_forward
- Define the following as they apply to an enzymatic reaction. Give an example of each. a. Enzyme-limited: b. Substrate-limited:arrow_forwardThe figure displays the relationship between initial rate of product formation and reactant concentration in an enzyme-catalyzed reaction with a fixed amount of enzyme. Which of the following statements best explains the shape of the rate curve at high reactant concentration?arrow_forwardCatalysis involves overcoming the activation energy barrier of a reaction. What are three ways by which enzymes can do this?arrow_forward
- Why is an enzyme highly specific for the type of reaction it will promote?arrow_forwardA researcher has developed an assay to measure the activity of an important enzyme present in pancreatic cells growing in culture. She adds the enzyme's substrate to a dish of cells and then measures the appearance of reaction products. The results are graphed as the amount of product on the y-axis versus time on the x-axis. The researcher notes four sections of the graph. For a short period of time, no products appear (section A). Then (section B) the reaction rate is quite high (the slope of the line is steep). Next, the reaction gradually slows down (section C). Finally, the graph line becomes flat (section D). Draw and label the graph, and propose a model to explain the molecular events occurring at each stage of this reaction profile.arrow_forwardList three ways to alter the rate of an enzyme-mediated reaction.arrow_forward
