What is the primary role of enzymes?

Enzymes play a crucial role in biochemical reactions by acting as catalysts that speed up the rate of these reactions without being consumed in the process. They achieve this by lowering the activation energy required for a reaction to occur, making it easier for substrates to convert into products. Enzymes are highly specific, meaning they only catalyze specific reactions or types of reactions, ensuring that metabolic processes happen efficiently and precisely within the cells.

This catalytic function is vital for numerous biological processes, including digestion, DNA replication, and cellular respiration, among others. By facilitating these reactions, enzymes help maintain the necessary conditions for life and support the complex network of biochemical pathways in living organisms.
