What is the function of enzymes in the human body?

Enzymes play a crucial role in the human body by speeding up chemical reactions. They are biological catalysts, which means they facilitate and accelerate the rate of reactions without being consumed in the process. This is essential for various metabolic processes, including digestion and energy production, allowing the body to function efficiently.

For instance, enzymes break down nutrients from food into simpler molecules, enabling the body to absorb them effectively. Additionally, they are involved in numerous biochemical pathways, ensuring that necessary reactions occur at rates that sustain life. Without enzymes, many biological processes would be far too slow to support life as we know it. Thus, the key function of enzymes is their ability to increase the speed of chemical reactions, making them vital for maintaining bodily functions.
