Enzymes Which of the following is false statement with regard to comparison between Serine and HIV proteases? Both forms an acyl-enzyme intermediate Both require water to complete the catalytic cycle Both use nucleophilic attack to hydrolyze the peptide bond Both show specificity for certain amino acid sequences Both forms an acyl-enzyme intermediate Both require water to complete the catalytic cycle Both use nucleophilic attack to hydrolyze the peptide bond Both show specificity for certain amino acid sequences ANSWER DOWNLOAD EXAMIANS APP
Enzymes Enzyme-driven metabolic pathways can be made more efficient by grouping enzymes into free-floating, multienzyme complexes fixing enzymes into membranes so that they are adjacent to each other All of these concentrating enzymes within specific cellular compartments grouping enzymes into free-floating, multienzyme complexes fixing enzymes into membranes so that they are adjacent to each other All of these concentrating enzymes within specific cellular compartments ANSWER DOWNLOAD EXAMIANS APP
Enzymes Before they can react, many molecules need to be destabilized. This state is typically achieved through oxidizing the molecules by removing electrons changing the reaction from a biosynthetic to a catabolic pathway the input of a small amount of activation energy changing the three-dimensional shape of the molecule oxidizing the molecules by removing electrons changing the reaction from a biosynthetic to a catabolic pathway the input of a small amount of activation energy changing the three-dimensional shape of the molecule ANSWER DOWNLOAD EXAMIANS APP
Enzymes The role of Asp 102 and His 57 during trypsin catalysis is to function as a proton shuttle keep the specificity pocket open neutralize the charge on the other's side chain clamp the substrate into the active site function as a proton shuttle keep the specificity pocket open neutralize the charge on the other's side chain clamp the substrate into the active site ANSWER DOWNLOAD EXAMIANS APP
