Original practice preview

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

Example 1 · difficulty 2/5

The respiratory pathway is described as an amphibolic pathway because it

A. functions only in the presence of oxygen
B. participates in both the breakdown and the synthesis of organic compounds
C. is distributed between the cytoplasm and the mitochondria
D. generates both ATP and reduced coenzymes simultaneously

Example 2 · difficulty 3/5

Within a single turn of the Krebs cycle, ATP (or GTP) is produced directly by substrate-level phosphorylation during the conversion of

A. citric acid to cis-aconitic acid
B. succinic acid to fumaric acid
C. malic acid to oxaloacetic acid
D. succinyl-CoA to succinic acid

Example 3 · difficulty 1/5

Which statement best describes cellular respiration?

A. Food substances are oxidised within cells, and the released energy is trapped mainly as ATP
B. Carbon dioxide is converted into glucose using light energy
C. Oxygen is produced by splitting water in every living cell
D. Organic food is transported from leaves to storage organs

Frequently asked questions

Are these official NEET 2018 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 2018 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.
