What are Enzymes?

Correct option is A

The correct answer is (a) They convert complex organic substances into simpler molecules.
· Enzymes are biological catalysts that accelerate chemical reactions in living organisms. They help convert complex organic substances into simpler molecules, facilitating processes like digestion, metabolism, and energy production.
· Enzymes are highly specific in their action and work under specific conditions (temperature and pH).
· They play a crucial role in both breaking down molecules (catabolic reactions) and building up molecules (anabolic reactions).
Additional Knowledge:
· They are highly soluble in water: While many enzymes are soluble in water, this is not their defining characteristic. The main role of enzymes is to catalyze biochemical reactions.
· They resist the attack of viral diseases: Enzymes themselves do not provide resistance against viral diseases. The immune system, including antibodies and other components, plays a role in resisting viral infections.
· They are made up of organic bases and phosphate ions: This description fits the components of nucleic acids (like DNA and RNA) rather than enzymes, which are composed primarily of amino acids forming protein structures.
