Question 13 Marks
Given below are two reactions.
(a) C6H12O6+ 6O2 → 6CO2 + 6H2O + Energy
(b) C6H12O6 → 2C2H5OH + Energy
Now, answer the following questions
(i) What processes are taking place in reactions (a) and (b)?
(ii) Where do these reactions take place? Name the organisms involved.
(iii) Mention three differences between the two reactions.
(a) C6H12O6+ 6O2 → 6CO2 + 6H2O + Energy
(b) C6H12O6 → 2C2H5OH + Energy

| Aerobic respiration | Anaerobic respiration |
| (i) It takes place in the presence of oxygen. | (i) It takes place in the absence of oxygen, |
| (ii) It produces a considerable amount of energy. | (ii) Lesser energy is produced during this process. |
| Aerobic respiration | Anaerobic respiration |
| Oxygen is required for this type of respiration to take place. | No requirement of oxygen in this process. |
| It involves the exchange of gases between the organism and the outside environment. | Exchange of gases is there but oxygen gas does not take part. |
| Process of respiration takes place in the cyt oplasm and the mitochondria. | Takes place in the cytoplasm only. |
