ALipase, amylase, pepsin and cellulase
BSucrase, pepsin, lipase and peptidase
CPepsin, peptidase, trypsin and lipase
DAmylase, sucrase, lactase and maltase
Answer & Solution
Correct answer: D. Amylase, sucrase, lactase and maltase
1. Each macromolecule class is hydrolysed by its own specific enzymes.
2. Carbohydrates are handled by amylase, sucrase, lactase or maltase.
3. Pepsin, peptidase and trypsin act on proteins, and lipase acts on lipids, so any list carrying them is mixed up.
4. Hydrolysis in the digestive system yields small molecules that intestinal cells can absorb easily.
