Question A biology teacher asked her students to give the end products of anaerobic respiration in plants/animals.
John said: Carbon dioxide and water.
Kabir said: Glucose and water vapour.
Sukhvinder said: Carbolic acid and lactic acid.
Aayush said: Lactic acid.
Who were correct?
- John and Kabir
- Kabir and Sukhvinder
- Sukhvinder and Aayush
- John and Aayush
Sukhvinder and Aayush
Reason — Anaerobic respiration is the breakdown of glucose in the absence of oxygen. The end products vary depending on the organism:
- In plants and yeast:
Glucose → Ethanol + Carbon dioxide + Energy - In animals (like humans during vigorous exercise):
Glucose → Lactic acid + Energy
As Aayush said Lactic acid so his answer is correct. Sukhvinder said Carbolic acid and lactic acid. Carbolic acid is wrong, but lactic acid is correct for animals. So, Sukhvinder's answer is partially correct.
