Frequently asked questions
What is the most-tested fact pattern in this chapter?
Matching each digestive enzyme to its source gland, site of action, and substrate/product — this single pattern accounts for a large share of NEET questions from Digestion and Absorption.
Are digestive disorders tested?
Yes, briefly — jaundice, diarrhoea, and peptic ulcers are occasionally referenced, but enzyme/organ-function facts dominate over disorder-based questions.
How does this chapter connect to Biomolecules?
The macromolecules broken down here (proteins, carbohydrates, fats) are the same ones characterised in the Class 11 Biomolecules chapter — understanding both together strengthens recall.
