A catalyst accelerates a chemical reaction in a cell.
A catalyst is a substance that increases the rate of a chemical reaction without undergoing any permanent chemical change itself.
Catalysts work by lowering the activation energy required for a reaction to occur. Activation energy is the energy barrier that must be overcome for a reaction to proceed.
By reducing the activation energy, a catalyst makes it easier for reactant molecules to come together and undergo chemical transformations, ultimately speeding up the reaction.
Catalysts are essential in biological systems as they enable various biochemical reactions to occur at the relatively mild conditions found inside cells, which would otherwise require higher temperatures or longer reaction times without catalysis.
In cells, enzymes are the most common type of catalysts. Enzymes are highly specific protein molecules that catalyze specific biochemical reactions, ensuring the efficient and precise functioning of cellular processes.
