Answer:
The correct answer is C in presence of oxygen production of acetyl CoA,TCA cycle and electron transport chain occur in a proper order.Whether in absence of oxygen lactic acid fermentation or alcoholic fermentation occurs.
Explanation:
Aerobic respiration occur in presence of oxygen which involves glycolysis,TCA cycle and electron transport chain.Aerobic respiration result in the catabolism of glucose to generate CO2,H2O and ATP.
But in absence of oxygen or during anaerobic condition pyruvic acid is converted to either lactic acid by pyruvate dehydrogenase or to ethanol through alcoholic fermentation.
They are semi-permeable because they can diffuse and pass through the plasma membrane easily.
