Textbook Question
Chapter 6, Problem 6.8PS
QUANTITATIVE Turnover Number. Carbonic anhydrase catalyzes the reversible hydration of carbon dioxide to form bicarbonate ion:
As we will discover in Chapter 8, this reaction is important in the transport of carbon dioxide from body tissues to the lungs by red blood cells. Carbonic anhydrase has a molecular weight of 30,000 and a turnover number (kcat value) of 1 × 106 sec−1. Assume that you are given 1 mL of a solution containing 2.0 μg of pure carbonic anhydrase.
- (a) At what rate (in millimoles of CO2 consumed per second) will you expect this reaction to proceed under optimal conditions?
- (b) Assuming standard temperature and pressure, how much CO2 is that in mL per second?

- Enzymes catalyze chemical reactions. What constitutes the active site of an enzyme? What are the turnover number (kcat), the Michaelis constant (Km), and the maximal velocity (Vmax) of an enzyme? The kcat (catalytic rate constant) for carbonic anhydrase is 5 × 105 molecules per second. This is a “rate constant,” but not a “rate.” What is the difference? By what oncentration would you multiply this rate constant in order to determine an actual rate of prod- uct formation (V)? Under what circumstances would this rate become equal to the maximal velocity (Vmax) of the enzyme?arrow_forwardNo free lunch.

- Between two extremes. What is the role of a thioester in the formation of ATP in glycolysis?arrow_forwardYou happen to pass a bar. Distracted by your entrance into the bar, one of the humans inadvertently drank a beverage containing 80 ml methanol. Unfortunately, no medical personnel are on the station, and you do not have access to sickbay. Assume that methanol and ethanol have densities of 0.79 g/ml, and that the alcohols distribute themselves rapidly over the total volume of 73 liters of body fluids of your host. A quick check of the biochemistry textbook that you always carry with you when traversing the promenade reveals that the Km of alcohol dehydrogenase for ethanol is 1 mM and for methanol the Km is 10 mM, and reminds you that alcohol dehydrogenase converts ethanol into acetaldehyde (which can then be converted to acetyl-CoA). Alcohol dehydrogenase also converts methanol into formaldehyde, which is quite toxic to humans. Ingesting 80 ml of methanol will permanently harm the human unless you intervene.b.

Discuss (or illustrate) the pathway and reactions that cause the rapid increase in lactate concentration during the sprint. b. What causes the slow decline in lactate concentration after the sprint? Why does the decrease occur more slowly than the rapid increase? c.
