Digestion and Absorption — NEET/JEE Questions, Notes & Weightage
Class 11 Human Physiology NEET weightage: Very High 0 questions
Covers the human digestive system, the digestive enzymes secreted at each step, and absorption mechanisms in the small intestine. Enzyme-and-substrate matching (which enzyme acts on what, and where) is the most reliable and recurring NEET question type in this chapter.

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.
