Airsoft guns can be modified to increase pellet velocity, rate of fire, reliability, or accuracy/range. For an electric airsoft gun, the pellet velocity can be increased by two different methods. The first is upgrading the inner barrel of the gun.
In this juice are enzymes (including lipase, protease, and amylase) required for the digestion and absorption of food. Lipase (along with bile) helps digest fats. Amylase (secreted by the salivary glands and pancreas) breaks down starch molecules into more absorbable sugars. The proteases secreted by the pancreas (trypsin, chymotrypsin, and carboxypeptidase) break protein molecules into single amino acids.
There are six main groups of enzymes-hydrolases, isomerases, ligases, lyases, oxidoreductases, and transferases. The enzymes involved in food decomposition and in the digestive process are hydrolases. They break down proteins (proteases), carbohydrates (carbohydrases or amylases), and fats (lipases). Plants also contain enzymes to break down fiber (cellulases).
