What are enzymes? What is the importance of enzymes for living beings?
Enzymes are proteins that are catalysts of chemical reactions. From Chemistry it is called that catalysts are non-consumable substances that decrease the activation energy essential for a chemical reaction to happen.
Enzymes are highly specific to the reactions they catalyze. They are of essential importance for life because most chemical reactions of the cells and tissues are catalyzed by enzymes. Without enzymatic action those reactions would not happen or would not happen in the needed speed for the biological processes in which they participate.
