Chemical Reactions in Metabolic Processes In order for a chemical reaction to take place, the reacting molecules (or atoms) must  first collide and then have sufficient energy (activation energy) to trigger the formation of  new bonds. Although many reactions can occur spontaneously, the presence of a  catalyst accelerates the rate of the reaction because it lowers the activation energy  required for the reaction to take place. A  catalyst  is any substance that accelerates a  reaction but does not undergo a chemical change itself. Since the catalyst is not  changed by the reaction, it can be used over and over again. Chemical reactions that occur in biological systems are referred to as  metabolism. Metabolism  includes the breakdown of substances (catabolism), the  formation of new products (synthesis or anabolism), or the transferring of energy from  one substance to another. Metabolic processes have the following characteristics in

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
