Question

For the fats to be respired, what are they broken into?

(a) Glycerol and fatty acids

(b) Glycerol and ethanol

(c) Fatty acids only

(d) Glycerol only

This question was posed to me during an interview for a job.

This intriguing question originated from Plants Respiration in portion Respiration in Plants of Biology – Class 11

Answer 1

Correct answer is (a) Glycerol and fatty acids

For explanation I would say: Fats would need to be broken down into glycerol and fatty acids first. If fatty acids were to be respired they would first be degraded to acetyl CoA and enter the pathway.
