Enzymes and activation energy (video) | Khan Academy
Uncover how enzymes accelerate biochemical reactions by reducing activation energy. Learn about catalytic strategies such as acid/base and covalent catalysis, and grasp the concept of transition states.
Activation energy (article) | Khan Academy
The activation energy shown in the diagram below is for the forward reaction (reactants → products), which is exergonic. If the reaction were to proceed in the reverse direction (endergonic), the …
