Practice questions on the electron transport system and oxidative phosphorylation, the final stages of cellular respiration that produce most of the ATP in cells.
Glycolysis occurs in the cytoplasm and leads to the breakdown of glucose into pyruvate.

Oxygen acts as the final hydrogen acceptor in aerobic respiration, combining with electrons and protons to form water.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Electron Transport System and Oxidative Phosphorylation
The Krebs cycle does generate ATP through substrate-level phosphorylation.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Electron Transport System and Oxidative Phosphorylation
The Electron Transport Chain generates ATP through oxidative phosphorylation, not substrate-level phosphorylation.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Electron Transport System and Oxidative Phosphorylation
The Electron Transport Chain produces the highest amount of ATP by oxidative phosphorylation.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Electron Transport System and Oxidative Phosphorylation
Oxygen acts as the final electron acceptor in the electron transport system, combining with hydrogen to form water.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Electron Transport System and Oxidative Phosphorylation
ATP synthase does not require NADH directly; it uses the proton gradient created by the Electron Transport Chain.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Electron Transport System and Oxidative Phosphorylation
Oxidative phosphorylation occurs after the Krebs cycle, using electrons from NADH and FADH₂.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Electron Transport System and Oxidative Phosphorylation
NADH and FADH₂ donate electrons to the Electron Transport Chain, leading to ATP production through oxidative phosphorylation.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Electron Transport System and Oxidative Phosphorylation
ATP releases energy when it is hydrolyzed to ADP, which is used in various cellular processes.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Electron Transport System and Oxidative Phosphorylation
ATP is produced in glycolysis, the Krebs cycle, and oxidative phosphorylation, not just glycolysis.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Electron Transport System and Oxidative Phosphorylation
Complex IV (Cytochrome c oxidase) transfers electrons to oxygen, forming water.
