Quick Answer

The most repeated Biochemistry topics in NEET PG and INI-CET (2017–2026) are Molecular Biology & Genetics (69 questions), Clinical Biochemistry and Nutrition (58 questions) and Proteins (43 questions), out of 285 recalled Biochemistry questions from 18 papers in the Kinase bank. Molecular Biology & Genetics appeared in 16 of 18 papers.

Which Biochemistry topics are asked most?

Topics are ranked by recalled questions across NEET PG and INI-CET. "Asked in" counts the exam-year papers (out of 18 with Biochemistry questions) in which the topic appeared at least once; "Share" is the topic's part of all 285 Biochemistry questions.

Trend = change in the topic's share of Biochemistry questions from 2018 to 2026 on a fitted line; ±5 percentage points or more is rising/falling. Topics with fewer than 10 questions get no label ("—"). 3 Biochemistry questions are not yet filed under a topic and are left out of the table.

How many Biochemistry questions appear each year?

Biochemistry makes up 5.3% of all recalled questions in the bank. Its share was highest in 2021 (36 of 596 recalled questions that year), and its overall share trend since 2018 is steady (-0.8 pts). Bars differ in height partly because some years' papers were recalled more fully than others.

NEET PGINI-CET / AIIMS PGRecalled questions per calendar year; the number recalled differs by year.

What kind of Biochemistry questions are asked?

Our editors tag each question's format (a question can carry several). 28 of the 285 Biochemistry questions (10%) have an image in the stem. The most common format tags:

How to read these numbers: previous-year papers are not released in full, so they are rebuilt from candidates' memory-based recalls and every question is reworded. The counts reflect Kinase's recall bank (snapshot 2026-09-30), not an official NBEMS or AIIMS subject or topic breakdown. A recalled paper can be incomplete, so compare shares rather than raw counts between years.

Methodology: Each question is counted once per exam-year, even when the same paper is mapped to several courses or tests. Where editors tagged recall provenance in a paper, untagged extra practice items are left out. See the all-subjects page for the full method, the list of papers and the cross-subject top 25.

Frequently Asked Questions

What are the most repeated Biochemistry topics in NEET PG and INI-CET?▼
In Kinase's recall bank (2017–2026), the most repeated Biochemistry topics are Molecular Biology & Genetics (69 questions), Clinical Biochemistry and Nutrition (58 questions), Proteins (43 questions). Molecular Biology & Genetics was asked in 16 of 18 papers.
How many Biochemistry questions come in NEET PG and INI-CET?▼
Kinase has 285 recalled Biochemistry questions from 18 papers: 117 from NEET PG and 168 from INI-CET / AIIMS PG. That is 5.3% of all recalled questions in the bank. The per-year chart shows how the count varies with the size of each recalled paper.
Which Biochemistry topics appear in every paper?▼
No single Biochemistry topic appears in every one of the 18 papers; Molecular Biology & Genetics comes closest (16 of 18 papers).
Which Biochemistry topics are rising or falling?▼
Rising share since 2018: Lipids, Carbohydrates. Falling share: Clinical Biochemistry and Nutrition, Proteins. A trend is a change of 5 or more percentage points in the topic's share of Biochemistry questions.
Are these official Biochemistry weightage figures?▼
No. NBEMS and AIIMS do not publish topic-wise breakdowns. These counts come from memory-based recalls in the Kinase question bank, reworded by our editors, so they show what candidates remembered — a practical signal of what repeats, not an official statistic.
How should I use this list to revise Biochemistry?▼
Revise the topics at the top of the table first and practise their previous-year questions, then cover the rest of the subject — lower-ranked topics still appear. Use the NEET PG and INI-CET Biochemistry PYQ pages for practice questions with explanations.
