Practice questions covering fermentation processes like alcoholic and lactic acid fermentation, as well as amphibolic pathways that connect metabolic processes.
Glycolysis occurs in the cytoplasm and is the first step in both aerobic and anaerobic respiration.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Fermentation - Alcoholic and Lactic Acid and Amphibolic Pathway
Fermentation occurs in the absence of oxygen and does not involve the Electron Transport Chain.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Fermentation - Alcoholic and Lactic Acid and Amphibolic Pathway
Aerobic respiration produces a net gain of 38 ATP molecules per glucose molecule.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Fermentation - Alcoholic and Lactic Acid and Amphibolic Pathway
During alcoholic fermentation, pyruvate is converted into ethanol and carbon dioxide.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Fermentation - Alcoholic and Lactic Acid and Amphibolic Pathway
Aerobic respiration occurs in both prokaryotic and eukaryotic cells.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Fermentation - Alcoholic and Lactic Acid and Amphibolic Pathway
Pyruvate decarboxylase catalyzes the conversion of pyruvate into ethanol during alcoholic fermentation.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Fermentation - Alcoholic and Lactic Acid and Amphibolic Pathway
The Krebs cycle is considered amphibolic because it involves both catabolic (breakdown of molecules) and anabolic (synthesis of precursors) processes.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Fermentation - Alcoholic and Lactic Acid and Amphibolic Pathway
The correct equation for aerobic respiration is: C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + Energy.
Ref: NCERT Class 11 Biology Chapter 12: Respiration in Plants Fermentation - Alcoholic and Lactic Acid and Amphibolic Pathway
Fermentation occurs in the absence of oxygen and produces ethanol or lactic acid along with carbon dioxide.
