Match List-I with List-II: (NEET 2024) List-I: A. Citric Acid Cycle B. Glycolysis C. Electron Transport System D. Proton Gradient List-II: I. Cytoplasm II. Mitochondrial Matrix III. Intermembrane Space of Mitochondria IV. Inner Mitochondrial Membrane Choose the correct answer from the options given below:
Answer & NCERT explanation
Correct answer: B — A–II, B–I, C–IV, D–III
Without seeing the specific Lists, I cannot provide detailed explanation. However, the correct answer b: A-II, B-I, C-IV, D-III suggests specific biochemical pairings. In NEET respiration questions, these typically involve matching enzymes with their substrates, products with pathways, or organelles with their functions in cellular respiration.

What is interesting to note is that the first process takes place in the matrix of the mitochondria while the second process is located on the inner membrane of the mitochondria.
This concept tests whether students understand that cellular respiration involves two distinct locations within mitochondria. The first process (Krebs cycle/citric acid cycle) occurs in the matrix, while the second process (electron transport chain/oxidative phosphorylation) is embedded in the inner membrane. Students commonly confuse where these processes happen or think they all occur in one location. Remember: matrix = Krebs cycle (soluble enzymes), inner membrane = ETC and ATP synthase (membrane proteins). NEET frequently asks location-based questions to differentiate between students who memorize diagrams versus those who understand compartmentalization of cellular respiration.
