The biological catalysts which help in the breakdown of food in humans known as _____.
Enzymes
The question defines biological catalysts that break down food in humans and asks for the correct term.
A catalyst speeds up a chemical reaction without being used up; in living bodies these are called biological catalysts.
In humans, enzymes are these biological catalysts; they are mostly proteins that convert complex food molecules into simpler, absorbable units during digestion.
Each enzyme is specific: salivary and pancreatic amylase break starch into sugars, proteases (like pepsin and trypsin) break proteins into amino acids, and lipase breaks fats into fatty acids and glycerol.
Lymph is a body fluid involved in immunity and fat transport, mucus is a protective lubricating secretion, and bile only emulsifies fats into smaller droplets, it is not itself an enzyme.
Because only enzymes act as the catalysts that chemically digest food, they are the required answer.
Hence, the answer is Enzymes.
