2 Board Biology previous year questions on Respiration in Plants — options free on every question; 1 include the answer & explanation free, the rest unlock with PYQ Pass.
Match List I with List II.
| List I | List-II | ||
| A. | Citric acid cycle | I. | Cytoplasm |
| B. | Glycolysis | II. | Mitochondrial matrix |
| C. | Electron transport system | III. | Intermembrane space of mitochondria |
| D. | Proton gradient | IV. | Inner mitochondrial membrane |
Choose the correct answer from the options given below:
A-II, B-I, C-IV, D-III
-
A. Citric acid cycle → Mitochondrial matrix (II):
The citric acid (Krebs) cycle occurs in the mitochondrial matrix where enzymes for the cycle are located. -
B. Glycolysis → Cytoplasm (I):
Glycolysis takes place in the cytoplasm and breaks down glucose into pyruvate. -
C. Electron transport system → Inner mitochondrial membrane (IV):
The ETS (electron transport chain) is embedded in the inner mitochondrial membrane. -
D. Proton gradient → Intermembrane space (III):
During electron transport, protons (H⁺) are pumped into the intermembrane space, creating a proton gradient used for ATP synthesis.
The complex II of mitochondrial electron transport chain is also known as
Options are free to see. Unlock the correct answer and full explanation with Pass.
