Answer:

mouth, stomach

Step-by-step explanation:

The carbohydrates start the digestion in the mouth, with the enzymes dissolved in the saliva, and during the rest of the digestive system it continues until the intestine.

Most of the digestion of lipids is in the intestine, with the lipid enzymes that come from the bile. But it starts in the mouth with the absorption of the small ones.

The chemical digestion of the proteins begins in the stomach because the peptide enzyme it turns active with the acidic environment of the stomach.
