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 oxidizing the molecules by removing electrons the input of a small amount of activation energy changing the three-dimensional shape of the molecule changing the reaction from a biosynthetic to a catabolic pathway oxidizing the molecules by removing electrons the input of a small amount of activation energy ANSWER DOWNLOAD EXAMIANS APP

Enzymes Which of the following is false statement with regard to comparison between Serine and HIV proteases? 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 Both forms an acyl-enzyme intermediate Both require water to complete the catalytic cycle ANSWER DOWNLOAD EXAMIANS APP
