This Class 11 Biology Chapter 19 Chemical Coordination and Integration NCERT Exemplar Book PDF is the official 2026-27 NCERT Exemplar, checked against the latest edition.

What the Chemical Coordination and Integration Exemplar Covers

The Exemplar tests the same chapter as the textbook but at a higher level of difficulty. Its questions probe the human endocrine glands and their hormones, the hypothalamus and pituitary link, the mechanism of hormone action and the feedback control of secretion. Because this chapter is a long list of glands, hormones and their effects, the Exemplar checks whether students can match each gland with its hormone, trace a feedback loop, and tell a steroid hormone from a protein hormone by how it acts.

• The human endocrine system, from the hypothalamus and pituitary to the thyroid, parathyroid, adrenal, pancreas and gonads.
• The major hormones, their target organs and the disorders of hyper and hyposecretion.
• The mechanism of hormone action for protein and steroid hormones, and feedback regulation.

Why Practise the Exemplar for This Chapter

The Exemplar bridges the gap between the NCERT textbook and the level of a competitive exam. For chemical coordination and integration, its questions are close to the style asked in NEET and CUET, where a single detail about a gland, a hormone or a feedback loop can decide a mark. Because this chapter is a long list of glands and their hormones, the Exemplar is where students meet the application-based questions and assertion-reason sets that a plain reading of the textbook rarely throws up.

• Higher-order questions on the mechanism of hormone action that the textbook exercises do not cover.
• Assertion-reason sets that sharpen your grip on feedback control and tropic hormones.
• MCQs on the glands, their hormones and the related disorders at exam level.

How to Use the Exemplar for Chemical Coordination and Integration

Attempt the Exemplar only after you have finished the NCERT textbook chapter and its back exercises. Treat it as your second, harder pass over the chapter. Because much of this chapter is a gland-and-hormone list, students gain the most by building a table of gland, hormone and function and writing out each feedback loop rather than only marking the option, so the links stay fixed in memory for the exam.

• Solve the MCQs first to test recall of glands and hormones, then move to assertion-reason.
• Attempt each short and long answer fully before checking the Exemplar Solutions.
• Build a table of gland, hormone, target and disorder, and revise it daily.
• Mark the questions you got wrong and redo them after two days.

More than 10,000 Class 11 students used these Collegedunia NCERT resources during the 2026 boards and NEET preparation. Their feedback shaped how we present this chapter, and the message on Chapter 19 was consistent: the Exemplar is what turns the long gland-and-hormone list into exam-ready recall.

• Students rated the questions on hormone action and feedback as the most useful part for NEET.
• Many said the Exemplar MCQs on the glands and hormones matched the board and NEET questions they later saw.
• Students preparing for CUET found the short-answer terms a fast way to revise the whole chapter.
