- A. 0.75
- B. 1.33
- C. 1.00
- D. 4.00

NEET 2017 Biology Respiration in Plants Questions
Use this page to connect the official 2017 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
glycolysis, fermentation, aerobic respiration, respiratory balance and amphibolic pathways.
Original practice preview
These are current-syllabus NeetVellum questions, shown separately from historical-paper provenance.
Example 2 · difficulty 3/5
When one molecule of glucose is completely oxidised through glycolysis, the link reaction and the Krebs cycle, the total number of NADH molecules generated is
- A. 6
- B. 8
- C. 10
- D. 12
Example 3 · difficulty 4/5
During oxidative phosphorylation, FADH2 yields fewer ATP molecules than NADH because FADH2
- A. enters the electron transport chain at complex II, bypassing complex I, so fewer protons are pumped across the inner membrane
- B. is unable to transfer its electrons to ubiquinone
- C. gets oxidised within the mitochondrial matrix without ever engaging the electron transport chain
- D. donates a single electron rather than a pair of electrons
The evidence-first practice loop
- 1. Verify provenanceOfficial paper and final key before accepting a PYQ label.
- 2. Attempt closed-bookExpose the concept or execution gap before rereading.
- 3. Repair and returnClassify the miss and re-practice after a delay.

Frequently asked questions
Are these official NEET 2017 Biology Respiration in Plants 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.
