Which fact is most important in explaining how enzymes speed reactions? Very low potential energy tends to make molecules unstable. High-energy collisions are less common than low-energy collisions. It takes less energy to break a hydrogen bond than a covalent bond. Large molecules collide more energetically than small molecules. Every reaction step adds to the time required for the overall reaction. Study Enzyme Activity.
How Do Enzymes Work in the Human Body? Enzymes are proteins that allow certain chemical reactions to take place much quicker than the reactions would occur on their own. Enzymes function as catalysts, which means that they speed up the rate at which metabolic processes and reactions occur in living organisms. Usually, the processes or reactions are part of a cycle or pathway, with separate reactions at each step. Each step of a pathway or cycle usually requires a specific enzyme.
