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