Biochemistry produced 168 of the 3,251 recalled INI-CET and AIIMS PG questions in the Kinase bank (2018–2026), placing it 10th of 19 subjects. Here are the chapters those questions came from, and a short checklist of concepts to revise before Sunday 1 November 2026.
Key Takeaways
- ✓Most-asked Biochemistry chapters: Molecular Biology & Genetics, Clinical Biochemistry and Nutrition, Carbohydrates
- ✓About 5.2% of recalled INI-CET questions; AIIMS publishes no official subject weightage
- ✓Chapters taking a growing share recently: Carbohydrates, Lipids
- ✓The concept checklist below is editorial, written against the top chapters, not counted from the bank
1Most-asked Biochemistry chapters in INI-CET
Ranked by recalled INI-CET / AIIMS PG questions. “Papers asked” counts NEET-PG and INI-CET exam-years with at least one question on the chapter, out of the years with any question in Biochemistry; the trend is computed on all recalled questions in the subject.
The top three chapters account for about 66.1% of recalled INI-CET Biochemistry questions, so revising them well covers most of what has been asked. Carbohydrates and Lipids have taken a growing share of questions in recent years. Clinical Biochemistry and Nutrition and Proteins have a shrinking share, but still appear, so do not drop them.
| Chapter | INI-CET questions | Papers asked (NEET-PG + INI-CET) | Trend (all recalls) |
|---|---|---|---|
| Molecular Biology & Genetics | 54 | 16 of 18 papers | Steady |
| Clinical Biochemistry and Nutrition | 30 | 16 of 18 papers | Falling |
| Carbohydrates | 27 | 16 of 18 papers | Rising |
| Lipids | 20 | 17 of 18 papers | Rising |
| Proteins | 19 | 17 of 18 papers | Falling |
| Enzymes and Porphyrins | 18 | 14 of 18 papers | Steady |
2Biochemistry questions by INI-CET year
| Year | Recalled INI-CET questions |
|---|---|
| 2018 | 21 |
| 2019 | 18 |
| 2020 | 20 |
| 2021 | 24 |
| 2022 | 28 |
| 2023 | 17 |

Years with fewer recalled questions usually reflect thinner recall coverage, not fewer questions in the paper.
3Biochemistry revision checklist
- ☐ DNA replication, transcription and translation
- ☐ PCR, blotting techniques and genetic disorders
- ☐ Vitamins: deficiency features and coenzyme roles
- ☐ Glycolysis, gluconeogenesis and glycogen storage disorders
- ☐ Lipoprotein metabolism and lipid storage disorders
- ☐ Enzyme kinetics and inborn errors of metabolism
4How to revise Biochemistry for INI-CET
Biochemistry rewards pathways and their disorders. Revise each pathway with its rate-limiting enzyme and the clinical condition caused by its defect, and keep molecular biology techniques in a comparison table.
Kinase Tip: See every Biochemistry chapter with year-by-year counts on the Biochemistry most-repeated topics page, then practise them on the INI-CET PYQ pages.
?Frequently Asked Questions
What are the most important Biochemistry topics for INI-CET?
In Kinase's recall bank of INI-CET / AIIMS PG questions (2018–2026), the Biochemistry chapters with the most questions are Molecular Biology & Genetics, Clinical Biochemistry and Nutrition, Carbohydrates. AIIMS does not publish an official topic list, so treat this as a revision order, not the full syllabus.
How many Biochemistry questions come in INI-CET?
AIIMS does not publish subject-wise weightage. In the recall bank, Biochemistry accounts for 168 of 3,251 recalled INI-CET questions (about 5.2%), ranking 10th of 19 subjects. Recall coverage varies by year, so read this as a rough share.
How should I revise Biochemistry in the last month before INI-CET?
Biochemistry rewards pathways and their disorders. Revise each pathway with its rate-limiting enzyme and the clinical condition caused by its defect, and keep molecular biology techniques in a comparison table. Solve the chapter's PYQs straight after revising it, and keep the final week for your error log, not new chapters.
