NEET 2022 Biology Chemical Coordination and Integration Questions

Use this page to connect the official 2022 paper with current Biology practice. NeetVellum does not claim a chapter appeared in that paper until the official question and final key have been mapped.

What to master

endocrine glands, hormones, feedback and common endocrine disorders.

Original practice preview

These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.

Example 1 · difficulty 3/5

A signalling molecule binds normally to its target-cell membrane receptor, but the cell cannot generate the required second messenger. Which outcome is most likely?

A. The gland necessarily begins secreting the molecule through a duct
B. The molecule automatically changes into a steroid and enters the nucleus
C. The intracellular response is greatly reduced despite normal receptor binding
D. Every non-target cell develops a response instead

Example 2 · difficulty 4/5

An inhibitory hypothalamic hormone acting on a particular anterior-pituitary cell type suddenly increases, while other influences remain unchanged. Which immediate pattern is most consistent with hypothalamic integration?

A. Secretion from that pituitary cell type rises, and its target gland is necessarily stimulated
B. The pituitary cell becomes exocrine and releases its product through a duct
C. All anterior-pituitary hormones stop because hypothalamic signals are non-specific
D. Secretion from that pituitary cell type falls, reducing its stimulatory influence on the corresponding target tissue

Example 3 · difficulty 2/5

A hypothalamic neurosecretory product reaching the adenohypophysis is inhibitory rather than releasing. What is its most direct expected effect?

A. A decrease in synthesis or secretion of the corresponding pituitary hormone
B. Axonal transport of that pituitary hormone into the hypothalamus
C. Immediate secretion of a hormone from the posterior pituitary
D. Increased responsiveness of all peripheral endocrine glands

Frequently asked questions

Are these official NEET 2022 Biology Chemical Coordination and Integration PYQs?

No. The previews are original NeetVellum practice questions. A historical item receives a PYQ label only after its official paper and authoritative final answer key are attached. Use the official archive for the source paper.

How should I use the NEET 2022 paper?

Solve the official paper under its original timing, verify against the final key, classify every miss, and then use the linked current-syllabus practice bank to repair the exposed concept.
