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