Web7 apr. 2024 · From Chemistry it is known that catalysts are non- consumable substances that reduce the activation energy necessary for a chemical reaction to occur. Enzymes are highly specific to the reactions they catalyze. They are of vital importance for life because most chemical reactions of the cells and tissues are catalyzed by enzymes. WebThis thermal energy is converted into kinetic energy, and more kinetic energy means that the particles move faster and collide with each other more frequently. In the case of enzyme-controlled reactions, the increase in kinetic energy means that the substrates will collide with the enzyme’s active site more frequently and form more enzyme–substrate …
