Question

Which of the following are correct about cellular respiration?
A. Cellular respiration is the breaking of C-C bonds of complex organic molecules by oxidation.
B. The entire cellular respiration takes place in Mitochondria.
C. Fermentation takes place under anaerobic condition in germinating seeds.
D. The fate of pyruvate formed during glycolysis depends on the type of organism also.
E. Water is formed during respiration as a result of O2 accepting electrons and getting reduced
Choose the correct answer from the options given below:

• A. A, C, D, E only
• B. A, B, E only
• C. A, B, C, E only
• D. B, C, D, E only

Answer 1

The Correct Option is A

Cellular respiration is characterized by the oxidation of complex organic molecules. Under anaerobic conditions, fermentation occurs, with the fate of pyruvate varying by organism. Oxygen acts as the final electron acceptor, resulting in the formation of water. Glycolysis, a stage of cellular respiration, occurs in the cytoplasm, not exclusively within mitochondria. Statements A, C, D, and E are accurate.
