- Multiple ChoiceA chemist has discovered a drug that blocks phosphoglucoisomerase, an enzyme that catalyzes the second reaction in glycolysis. He wants to use the drug to kill bacteria in people with infections. However, he cannot do this because __________.
- Multiple ChoiceOf the listed metabolic pathways, which is the only pathway found in all organisms?
- Open QuestionIn glycolysis, ________ is oxidized and ________ is reduced.a. NAD+ ... glucoseb. glucose ... oxygenc. ATP ... ADPd. glucose ... NAD+
- Open QuestionMAKE CONNECTIONS Step 3 in Figure 9.9 is a major point of regulation of glycolysis. The enzyme phosphofructokinase is allosterically regulated by ATP and related molecules (see Concept 8.5). Considering the overall result of glycolysis, would you expect ATP to inhibit or stimulate activity of this enzyme? Explain. (Hint: Make sure you consider the role of ATP as an allosteric regulator, not as a substrate of the enzyme.)
