Researchers analyzed a cell extract—a mixture of molecules isolatedfrom cells—and studied a chemical reaction in which a carbohydratewas broken down into smaller molecules. When they added a proteaseto the cell extract, they discovered that the protease greatly inhibited therate of the reaction. Based on this observation, you could conclude thatthe reaction isa. exergonic.b. endergonic.c. catalyzed by an enzyme.d. catalyzed by a ribozyme.e. Both b and c are true of this reaction.

In a highly high-temperature environment, you placed an enzyme and some substrates. You've seen that there hasn't been any reaction. Applying what you have learned on enzyme activity, how would you explain what occurred? A. The enzyme was not placed at a pH level that would allow it to react at its maximum rate. B. There are not enough enzymes for the reaction to occur. C. The enzyme may have denatured or broken down due to the high temperature of the environment, resulting in no reaction. D. There are not enough substrates for reaction to occur. Substrate concentration affects enzyme activity. Determine what would occur when there are too many substrates and fewer enzymes? A. No enzyme activity would occur. B. The reaction rate would continuously increase. C. The reaction would speed up tremendously. D. Maximal rate of reaction would occur. Enzyme activity mainly involves the active site and the substrate. How would you compare the active site from the substrate? A. The substrate…

SCIENTIFIC INQUIRY • DRAW IT A researcher has developedan assay to measure the activity of an important enzymepresent in pancreatic cells growing in culture. She adds theenzyme’s substrate to a dish of cells and then measures theappearance of reaction products. The results are graphed as theamount of product on the y-axis versus time on the x-axis. Theresearcher notes four sections of the graph. For a short periodof time, no products appear (section A). Then (section B) thereaction rate is quite high (the slope of the line is steep). Next,the reaction gradually slows down (section C). Finally, thegraph line becomes flat (section D). Draw and label the graph,and propose a model to explain the molecular events occurringat each stage of this reaction profile.
The probabiliy of a particular reaction occurring in a cell can be increased by A) having reactants contained within an organelle B) having reactants contained within an organelle with the necessary enzymes C) having low concentrations of the reactants D) having reactants with enthalphy with high enthalpy product(s)
Quite often, medications cannot be taken with grapefruit juice. This is becausegrapefruit juice blocks an enzyme responsible for metabolism of the drug. Chemicals ingrapefruit juice bind to the active site of the enzyme. What type of inhibition is this, andwhat would it do to the amount of medication in your blood? Why is this bad for you explain?
Why is an enzyme considered "specific"? A. Only one type of enzyme is found in our bodies B. Only certain enzymes can pass through the cell membrane C. Its active site must match the substrate to do its job D. The enzyme can only move from high to low concentration
Enzymes catalyze a chemical reaction by A. decreasing the amount of ATP required to activate a reaction B. increasing the amount of ATP required to activate a reaction C. slowing down the reaction to obtain more products D. increasing the reaction to obtain more products E. decreasing the amount of ATP required and obtaining more products.
Ben is studying an enzyme-catalyzed reaction. In the reaction, H+ ions are formed. He found that after a specific time, the reaction stopped, even though there was still a lot of substrate available in the mixture. a) Propose a hypothesis to explain why the reaction stopped.
Which of the following is not true about enzymes? a. They are consumed by the reactions they catalyze. b. They are usually made of amino acids. c. They lower the activation energy of chemical reactions. d. Each one is specific to the particular substrate(s) to which it binds.
In the experiment of Racker and Stoeckenius, bacteriorhodopsin wasoriented in such a way that it pumped H into a vesicle. Each vesicleactually contained many molecules of bacteriorhodopsin. How wouldthe results have been affected if 50% of the bacteriorhodopsin moleculespumped H into the vesicle and 50% pumped H out of the vesicles?a. The same amount of ATP would be made in the presence of light,and no ATP would be made in the dark.b. More ATP would be made in the presence of light, and no ATPwould be made in the dark.c. No ATP would be made in the presence of light, and no ATP wouldbe made in the dark. d.No ATP would be made in the presence of light, but some ATPwould be made in the dark.e. Some ATP would be made in the presence of light, and some ATPwould be made in the dark
How could you use the diversity of metabolic pathways that produce the same or similar products to critique this argument? Rank the steps from first to last. a. New enzymes cause modification of the pathway in an advantageous way. b. The biochemical pathway is gradually modified. c. A pathway exists and accomplishes some functions. d. An organism with cellular enzymes has mutations that allow new enzymes to arise.
SCIENTIFIC INQUIRY An experiment is designed to studythe mechanism of sucrose uptake by plant cells. Cells areimmersed in a sucrose solution, and the pH of the solutionis monitored. Samples of the cells are taken at intervals, andtheir sucrose concentration is measured. The pH is observedto decrease until it reaches a steady, slightly acidic level, andthen sucrose uptake begins. (a) Evaluate these results andpropose a hypothesis to explain them. (b) Predict what wouldhappen if an inhibitor of ATP regeneration by the cell wereadded to the beaker once the pH was at a steady level. Explain.
