Nowadays, the prevalence of sedentary lifestyles and high-caloric diets leads to an imbalance between energy intake and ...

Key chemistry topics include concentration vs. time data ... Arrhenius relationships; activation energy; reaction coordinate diagrams; and chemical mechanisms. The context of this module ties closely ...

Enzymes lower the activation energy necessary to transform a reactant into a product. On the left is a reaction that is not catalyzed by an enzyme (red), and on the right is one that is (green).

Activation energy is the minimum energy needed for ‘successful collisions’ where atoms within the reactants rearrange to form products. It can be represented on an energy level diagram.
