Q. What are the enzymes? What is the significance of enzymes for living beings?
Enzymes are proteins that are catalysts of the chemical reactions. From Chemistry it is known as catalysts that are non- consumable substances that reduce the activation energy necessary for a chemical reaction to occur.
Enzymes are highly specific to the reactions they catalyze. They are of fundamentally 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 occur in the required speed for the biological processes in which they participate.
