WebAug 28, 2024 · The answer is enzymes. Enzymes in our bodies are catalysts that speed up reactions by helping to lower the activation energy needed to start a reaction. Each enzyme molecule has a special place called the active site where another molecule, called the substrate, fits. WebThe lower the activation energy for a reaction, the faster the rate. Thus enzymes speed up reactions by lowering activation energy. Many enzymes change shape when substrates bind. This is termed "induced fit", meaning that the precise orientation of the enzyme required for catalytic activity can be induced by the binding of the substrate ... tema hut ri yang ke 77WebMar 4, 2024 · The activation energy required to achieve the transition state is a barrier to the formation of product. It is the minimum amount of energy required for a reaction to proceed. This barrier is the reason why the rate of many chemical reactions is very slow without the presence of enzymes, heat, or other catalytic forces. tema hut tni 2022
