Discuss how fats, glycerol and protein enter respiratory pathway.

1. 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 acetyl CoA and enter the pathway.

2. Glycerol would enter the pathway after being converted to phosphoglyceraldehyde.
