Both require water to complete the catalytic cycle All of these Both use a base to activate the nucleophile Both show specificity for certain amino acid sequences Both require water to complete the catalytic cycle All of these Both use a base to activate the nucleophile 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 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 changing the three-dimensional shape of the molecule changing the reaction from a biosynthetic to a catabolic pathway oxidizing the molecules by removing electrons ANSWER DOWNLOAD EXAMIANS APP
