Question
The mechanism in which the end product ofa pathway inhibits an the most precisely described as pathway is 45. A) metabolic inhibition. B) feedback inhibition. C) competitive inhibition. D) noncooperative inhibition E) reversible inhibition. This inhibition would most like involve the end product binding ware? 46. A. The active site B. The allosteric site C. The ATPase site D. The Ribosome E. The free energy site How might an amino acid change at a site distant from the active site of the enzyme 47. alter the enzyme's substrate specificity? A) by changing the enzyme's stability in the cell B) by changing the enzyme's location C) by changing the shape of the protein substrate specificity D) by changing the enzyme's pH optimum cannot alter the enzyme's E) an amino acid change away from the active site A molecule with the formula C18H3602 is probably a A) carbohydrate. B) fatty acid. C) protein. D) nucleic acid. E) hydrocarbon. vegetable oil" as the 49. The label on a container of margarine lists to vegetable oil? major ingredient. What is the result of adding hydrogens A) The hydrogenated vegetable oil has a lower melting point. B) The hydrogenated vegetable oil stays solid at room temperature. D) The hydrogenated vegetable oil has fewer trans fatty acids. another? E) The hydrogenated vegetable oil is less likely to clog arteries. different from There are 20 different amino acids. What makes one amino acid A) different side chains (R groups) attached to a carboxyl carbon B) different side chains (R groups) attached to the amino groups C) different side chains (R groups) attached to an a carbon D) different structural and optical isomers E) different asymmetric carbonsExplanation / Answer
45.FEED BACK INHIBITION : In this mechanism the enzyme binds to the substrate end product of the metabolic path way inhibits the earlier step.
46.Allosteric site : in feed back mechanism the end product binds to the allosteric site to slows down or stop the reaction.this allows the cells to produce lots af ATP.
48. A molecule with the formula C18H36O2 is probably a FATTY ACID. because therenis a oxygen so it cannot be a hydrocarbon,there is no nitrogen so it cannot be a protein , itz oxygen deficient so it might not be a carbohydrate.. so the structure containing molecule probably a fatty acid.
