Cellular respiration is one of the most fundamental and frequently tested topics in NEET, AIPMT, AIIMS, and other medical entrance examinations. This collection of 100 carefully curated multiple-choice questions (MCQs) has been compiled from previous year questions (PYQs) and closely follows the pattern, difficulty level, and concepts commonly asked over the years. Covering key areas such as glycolysis (EMP pathway), link reaction, Krebs cycle (TCA cycle), electron transport system (ETS/oxidative phosphorylation), fermentation, respiratory quotient (RQ), and regulatory aspects, these questions are ideal for quick revision, self-assessment, and building exam confidence.
