Original practice preview

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

Example 1 · difficulty 2/5

During thyroid surgery, all four parathyroid glands of a patient are accidentally removed. Which consequence is expected soon after the operation?

A. Marked rise in blood calcium due to unchecked bone resorption
B. Greatly increased urinary excretion of calcium ions
C. Compensatory overactivity of osteoblasts restoring calcium levels
D. Fall in blood calcium level leading to muscular tetany

Example 2 · difficulty 3/5

Steroid hormones such as cortisol and progesterone bring about their effects differently from peptide hormones like insulin mainly because they:

A. Bind to cell-surface receptors and use cyclic AMP as the second messenger
B. Diffuse through the plasma membrane and regulate gene expression by binding intracellular receptors
C. Are stockpiled in secretory vesicles and released in large bursts upon stimulation
D. Act exclusively on the very cells that secrete them

Example 3 · difficulty 1/5

Which statement about the human thymus gland is correct?

A. It grows steadily throughout life and remains fully active in old age
B. It releases thymosins that promote differentiation of T-lymphocytes involved in cell-mediated immunity
C. Its hormones chiefly raise blood glucose levels during stress conditions
D. It serves as the storage site for catecholamines released in emergencies

Frequently asked questions

Are these official NEET 2017 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 2017 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.
