Enzymes Which of the following is false statement with regard to comparison between Serine and HIV proteases? Both require water to complete the catalytic cycle Both use nucleophilic attack to hydrolyze the peptide bond Both forms an acyl-enzyme intermediate Both show specificity for certain amino acid sequences Both require water to complete the catalytic cycle Both use nucleophilic attack to hydrolyze the peptide bond Both forms an acyl-enzyme intermediate Both show specificity for certain amino acid sequences 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 the input of a small amount of activation energy changing the reaction from a biosynthetic to a catabolic pathway changing the three-dimensional shape of the molecule oxidizing the molecules by removing electrons the input of a small amount of activation energy changing the reaction from a biosynthetic to a catabolic pathway changing the three-dimensional shape of the molecule ANSWER DOWNLOAD EXAMIANS APP
