HUMAN NUTRITION (part 2)

How are carbohydrates digested?

• proteins using protease turns into polypeptides

• proteins using trypsin turns into polypeptides

• starch turns to maltose using pancreatic amylase then maltose turns to glucose using maltase enzyme

• fats using lipase turns into fatty acids and glicerols

Match the enzyme and the food substances changed.

• lipase; protein

• trypsin; fat

• pepsin and trypsin; protein
