Enzymes Before they can react, many molecules need to be destabilized. This state is typically achieved through changing the reaction from a biosynthetic to a catabolic pathway the input of a small amount of activation energy changing the three-dimensional shape of the molecule oxidizing the molecules by removing electrons changing the reaction from a biosynthetic to a catabolic pathway the input of a small amount of activation energy changing the three-dimensional shape of the molecule oxidizing the molecules by removing electrons ANSWER DOWNLOAD EXAMIANS APP
