The figure given below shows stalked particles on a region of mitochondrial cristae membrane.
Identify the process which occurs in the numbered regions.
| 1 | 2 | 3 | |
| (a) | Glycolysis | ADP synthesis | Krebs cycle |
| (b) | ATP synthesis | Krebs cycle | Electron transport chain |
| (c) | Krebs cycle | Oxidative phosphorylation | ATP synthesis |
| (d) | Electron transport chain | Glycolysis | Oxidative phosphorylation |

| (d) | Electron transport chain | Glycolysis | Oxidative phosphorylation |
Answer is : (b)
At position,
1 – The proton motive force is generated, powering ATP synthesis.
2 – Krebs cycle occurs oxidising two molecules of acetyl Co – A.
3 – Electron transport chain occurs coupled to proton transport across the inner membrane.
