NEET Biology Respiration in Plants Questions
Respiration in Plants practice focused on glycolysis, fermentation, aerobic respiration, respiratory balance and amphibolic pathways. Every preview below comes from NeetVellum's live original bank—not an unverified PYQ reconstruction.
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.
