Original practice preview

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

Example 1 · difficulty 4/5

Which set correctly represents the net products of glycolysis from one glucose molecule?

A. One pyruvic acid, four ATP and no NADH
B. Two acetyl coenzyme A, two ATP and two carbon dioxide
C. Two pyruvic acid, four net ATP and four NADH + H⁺
D. Two pyruvic acid, two net ATP, two NADH + H⁺ and two water molecules

Example 2 · difficulty 2/5

If three glucose molecules undergo glycolysis, what is the total net ATP gain from glycolysis alone?

A. 6 ATP
B. 9 ATP
C. 12 ATP
D. 18 ATP

Example 3 · difficulty 3/5

Which sequence correctly shows the early order of glycolytic intermediates?

A. Glucose → fructose-1,6-bisphosphate → glucose-6-phosphate → triose phosphates
B. Glucose → glucose-6-phosphate → fructose-6-phosphate → fructose-1,6-bisphosphate → triose phosphates
C. Glucose → pyruvate → glucose-6-phosphate → phosphoglyceraldehyde
D. Glucose → fructose-6-phosphate → pyruvate → fructose-1,6-bisphosphate

Frequently asked questions

Are these official NEET 2025 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 2025 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.
