NEET 2016 Biology Respiration in Plants Questions
Use this page to connect the official 2016 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 2/5
Anaerobic fermentation by yeast releases far less energy than aerobic respiration of the same amount of glucose mainly because
- A. glucose is incompletely oxidised, so most of its energy remains trapped in ethanol
- B. yeast lacks the enzymes needed to carry out glycolysis
- C. all the ATP generated in glycolysis is spent on reducing acetaldehyde to ethanol
- D. fermentation proceeds spontaneously without the involvement of enzymes
Example 3 · difficulty 2/5
In alcoholic fermentation, the enzyme responsible for converting pyruvic acid into acetaldehyde with the liberation of carbon dioxide is
- A. Alcohol dehydrogenase
- B. Pyruvate kinase
- C. Lactate dehydrogenase
- D. Pyruvate decarboxylase
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 2016 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 2016 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.
