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