The answer appears as a continuous sentence in NCERT. This is that sentence.

How this line gives the answer

0, emb=1.0, combined=1.0). Verified: high — The span explicitly states 'Chemiosmosis requires a membrane, a proton pump, a proton gradient and ATP synthase', which exactly matches option D and distinguishes it from incorrect options that mention electron gradient or NADP synthase.

We did this for 1,565 questions.

Every one traced to the exact sentence in NCERT that answers it, including 90% of the 2026 paper. Sit a mock on the real NEET 2027 computer interface and every mark you drop comes back with its line attached.
