Question

Identify the correct statement about respiration.
1. Without oxygen, cellular respiration is not possible in humans.​
2. Pyruvate is produced only in the case of aerobic respiration.​
3. Anaerobic respiration is possible in yeast and humans.​
4. The energy produced during cellular respiration is stored as ATP.

• A. 1, 2 & 3
• B. 3 & 4
• C. 1 & 4
• D. 2 & 3

Answer 1

The correct option is B 3 & 4

Cellular respiration, whether aerobic or anaerobic, is a metabolic process which converts nutrient into energy (stored in the form of ATP) and waste products. ​ Aerobic respiration uses the oxygen gathered during the process of respiration to facilitate ATP synthesis. ​
It always takes place in the presence of oxygen. Whereas, anaerobic respiration occurs in absence/lack of oxygen. In anerobic respiration yeast produces ethanol as end product whereas in muscles lactic acid is produced as end product.​
