EBK GENERAL, ORGANIC, AND BIOLOGICAL CH
- Match the enzyme name to the description of the type of reaction that it catalyzes. Each choice can only be used once. 1. Transfers a hydride ion in a redox reaction and decarboxylates. 2. Forms a double bond through a dehydration reaction. 3. Combines an aldose and a ketose together in the first step and then cleaves the intermediate molecule into a new aldose and new ketose. Is NOT sensitive to a Vitamin B1 deficiency. 4. Acts as both an enzyme and a scaffold for the formation of a glucose homopolymer. 5. Transfers the gamma phosphoryl group from ATP to a carbohydrate. answer choices: a. glycogen synthase b. glycogenin c. enolase d. PFK-1 e. G6P f. transketolase g. transketolase h. glyceraldehyde 3 phosphate dehydrogenase i. 6 phosphogluconate dehydrogenase Please answer completely will give rating surelyarrow_forwardIdentify the statements that are TRUE regarding Catabolic reactions. SELECT ALL THAT APPLY A. These reactions may also be called decomposition reactions B. These reactions create smaller products from larger reactants C. These reactions involve the formation of new bonds. D. These reactions typically release energy.arrow_forwardChoose the statement that best explains WHY the aldol condensation is considered base-catalyzed. a The base lowers the activation energy of the intermediates. b The base is used throughout the reaction but not consumed in the reaction, since it is regenerated in the final steps. C The base deprotonates the ketone, generating the nucleophile. d The base reacts with any acid that is present in the solution, accelerating the rate.arrow_forward
- Which of the followingdescribe superior properties of enzymes (biological catalysts) over traditional chemical catalysts? a.
