Regulatory mechanisms in metabolic pathways do which of the following?Group of answer choicesA) allow for pathways like amino acid synthesis and amino acid catabolism to occur at the same time to the same degreeB) allow an organism to use the right fuel at the right timeC) use one or two methods to regulate enzymes to control the flux through a given metabolic pathwayD) ensure there are more end products of biosynthetic pathways than neededE) all of the above

Which of the following best describes the role of catabolite repression in microbial metabolism?Question 18Answera.Increases the production of secondary metabolitesb.Prevents the synthesis of enzymes for secondary carbon sources when a preferred source is availablec.Activates the regulatory genes for enzyme productiond.Promotes the use of less preferred carbon sources

Which of the following enzymes are most likely to be regulated in glycolysis?Group of answer choicesA) all enzymes in glycolysis are potential regulation pointsB) enzymes that catalyze reversible steps are most likely to be regulatedC) hexokinase and pyruvate kinaseD) the first three enzymes of the pathway, since regulation is most efficient if it occurs at the beginning of a pathwayE) enzymes like aldolase, which catalyze big chemical changes like cleavage of C—C bonds
