MCQ
The enzymes are substances which:
  • A
    Are broken into simpler substances during digestion.
  • B
    Are made by the combination of carbohydrates.
  • C
    Break complexfood molecules into simpler food molecules.
  • D
    Break complex substances and they themselves undergo dissociation reactions.

Answer

  1. Break complexfood molecules into simpler food molecules.

Explanation:

Enzymes are macromolecular biological catalysts. Enzymes accelerate, or catalyze, chemical reactions.

The molecules at the beginning of the process are called substrates and the enzyme converts these into different molecules, called products.

Almost all metabolic processes in the cell need enzymes in order to occur at rates fast enough to sustain life.

Digestive enzymes are enzymes that break down polymeric macromolecules into their smaller building blocks. Enzymes are proteins.

So, they made of amino acids. They are not broken into simpler substances during digestion. They themselves can not undergo dissociation reactions.
