What enzyme is found in the mouth and the pancreas? What are the three steps in the digestion of protein?
Why is the name of the ions produced in the pancreas? (help please)

Mouth: Amylase

Pancreas: Pancreatic lipase, trypsin, Chymotrypsin.

2. Protein digestion starts in the mouth when the chewing process starts.

In the stomach, the hydrochloric acid and enzymes called proteases break it into chains of amino acids.

In the small intestine, a substance called BICARBONATE BUFFER then reduces the acidity of the digested food.

i would have to say autosomal

b. lithosphere, asthenosphere, mesosphere   is the answer most likely
