Which process involves the breakdown of large insoluble molecules into small water-soluble molecules using mechanical and chemical processes?

• A. Digestion
• B. Absorption
• C. Assimilation
• D. Metabolism

Answer: (A)

Breakdown of large insoluble molecules into small water-soluble molecules using both mechanical actions and enzymes is digestion. Mechanical digestion, such as chewing and stomach churning, physically breaks food into smaller pieces, while chemical digestion uses enzymes and acids to split big molecules into smaller units like sugars, amino acids, and fatty acids. These smaller, soluble molecules are then ready to be absorbed later in the small intestine. Aborption is about moving these nutrients into the bloodstream, assimilation is using them in body cells, and metabolism covers all the body’s chemical reactions. So the process described is digestion.
