Enzymes The proteolysis rate enhancement by chymotrypsin (~1010 folds) corresponds to a reduction in activation energy of about 88 kJ/mol 58 kJ/mol 49 kJ/mol 40 kJ/mol 88 kJ/mol 58 kJ/mol 49 kJ/mol 40 kJ/mol ANSWER DOWNLOAD EXAMIANS APP
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
