Enzymes: are biological molecules, specially proteins or RNA molecules that function as catalysts in living organisms. Catalysts are substrates that accelerate the are of chemical reactions without being consumed in the process. Enzymes play a critical role in nearly all biological processes, ranging from digestion and metabolism to DNA replication and cellular signaling. Enzymes are highly specific in their function and each enzyme typically catalyzes a specific chemical reaction or group of related reactions. They are involved in virtually all cellular reactions, including those that are essential for life, such as energy production, cell growth, and repair.
Why it is important
Facilitating chemical reactions. Enzymes facilitate chemical reactions in cells by lowering the activation energy required for a reaction to occur.
Enhancing reaction specificity. Enzymes are highly specific in their action, catalyzing specific reactions with high precision. This specificity allows enzymes to selectively accelerate specific reactions while leaving other cellular components unaffected. This precis control is critical for maintaining cellular components unaffected.
Increasing Reaction rates. They dramatically increase the rates of chemicals reactions in cells. Without enzymes, many essential cellular reactions would be too slow to sustain life.
Regulating cellular processes. They also play a crucial role in regulating cellular processes. They can be turned on or off in response to cellular signals allowing cells to respond to changing conditions and adapt to their environment.
