not the stomach
takes place in the mouth
The digestive system comprises two main organ groups: the alimentary canal and the accessory organs. The alimentary canal includes organs such as the mouth, esophagus, stomach, small intestine, large intestine, and anus, through which food passes and is processed. The accessory organs, which include the liver, pancreas, and gallbladder, produce enzymes and substances that aid in digestion but do not directly transport food. Together, these organ groups work to break down food, absorb nutrients, and eliminate waste.
The gastrointestional system digests food.
The pancreas is an organ that produces three different enzymes: amylase, lipase, and protease. Amylase helps break down carbohydrates, lipase helps break down fats, and protease helps break down proteins during digestion.
That is -ase. Enzymes are one type of proteins; enzymes have groups too. Proteases are enzymes that break down proteins.
Only the pancreas produces enzymes that break down all categories of digestible foods:1) along the brush of border enzymes, complete the digestion of starch (pancreatic amylase);2) carry out about half of protein digestion (via the action of trypsin, chymotrypsin, carboxypeptidase, and others);3) are totally responsible for fat digestion, because the pancreas is essentially the only source of lipases; and4) digest nucleic acids (nucleases).Source: Essentials of Human Anatomy and Physiology by Elaine N.

Complex molecules are broken down into simple molecules by the action of specialised proteins called enzymes. The three digestive enzymes are:amylases, which act on the carbohydratesproteases, which act on the proteinslipases, which act on the lipids

An alkyllysinase is any of a family of enzymes which catalyzes the removal of alkyl groups from lysine.
Enzymes can be classified as either simple enzymes or complex enzymes. 1) Simple enzymes are predominantly made up of proteins. 2) Complex enzymes are enzymes that require cofactors like iron or zinc ions to function properly.
Kinases are enzymes that add phosphate groups to proteins, activating or deactivating them in cellular signaling pathways. Phosphorylases are enzymes that catalyze the addition of phosphate groups to molecules, often involved in energy metabolism. Phosphatases are enzymes that remove phosphate groups from molecules, reversing the actions of kinases and phosphorylases in cellular signaling pathways.
Not sure what you mean by '3 types of digestion', but there are three major food groups (carbohydrates, proteins, and fats), and each has a different method of digestion by the digestive system.
