what is role of enzymes in animal digestion?

Enzymes play a very important role in animal digestion because they break down complex food into simple, absorbable substances.

Main Roles of Enzymes

  1. Break down food (chemical digestion)
    • Food like carbohydrates, proteins, and fats are too large to absorb.
    • Enzymes convert them into smaller molecules.
  2. Speed up digestion
    • Without enzymes, digestion would be extremely slow.
    • They act as biological catalysts (increase reaction rate).
  3. Specific action
    • Each enzyme works on a specific type of food (lock-and-key mechanism).
