Original practice preview

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

Example 1 · difficulty 3/5

In metabolically active tissues, which set of conditions favours dissociation of oxygen from oxyhaemoglobin (rightward shift of the O₂ dissociation curve)?

  • A. low pCO₂, low H⁺ concentration and low temperature
  • B. high pCO₂, high H⁺ concentration and high temperature
  • C. high pO₂, low pCO₂ and high temperature
  • D. low pO₂, low H⁺ concentration and low temperature

Example 2 · difficulty 3/5

In a healthy adult male, tidal volume = 500 mL, inspiratory reserve volume = 2500 mL, expiratory reserve volume = 1000 mL and residual volume = 1200 mL. His functional residual capacity (FRC) is closest to:

  • A. 1500 mL
  • B. 4000 mL
  • C. 2200 mL
  • D. 5200 mL

Example 3 · difficulty 3/5

Which statement regarding neural and chemical regulation of respiration in humans is correct?

  • A. The pneumotaxic centre in the pons can moderate the functioning of the respiratory rhythm centre located in the medulla oblongata
  • B. The respiratory rhythm centre lies in the cerebellum and generates the basic breathing rhythm
  • C. The chemosensitive area beside the rhythm centre is activated mainly by a fall in arterial pO₂
  • D. Receptors in the aortic arch and carotid artery respond exclusively to blood pH and ignore CO₂

The evidence-first practice loop

  1. 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
  2. 2. Attempt closed-bookExpose the concept or execution gap before rereading.
  3. 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions

Are these official NEET 2017 Biology Breathing and Exchange of Gases 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.
