Digestion

• Hydrolases - digestive enzymes
• Amylolytic - carbohydrates - splitting enzymes
• salivary amylase or ptyalin are from the salivary glands
• pancreas secrete pancreatic amylase
• invertases from goblet cell of the small intestine
• Proteases secreted as zymogens or inactive enzymes
• Pepsinongen from the gastric gland of the stomach
• Trypsinogen and Chymotrypsinogen from pancreas
• Gastric lipase from the stomach
• ribunuclease and deoxyribunuclease from pancreas
• Ptyalin - acts on starch in the oral cavity changing starch to maltose
• Pancreatic amylase - changing starch to maltose
• Maltose - changing it to glucose
• Lactase - changing it to glucose and galactose
• Sucrase - changing it to glucose and fructose
• Pepsinogen - activated to pepsin in the presence of HCL
• Trypsinogen - activated trypsin by enterokinase in small intestine
• Gastric lipase - acts on emulsified fats changing these fats acids
• Glycerol bile - emulsifies fats
• Nuclease - acts on nucleic acid changing these to nucleotides
• Phagocytosis - cell eating
• pinocytosis - cell drinking
• emeiocytosis - cell vomiting
• glucose and galactose by facilitated diffusion requiring the presence of high concentration of external Na

  ions
• vitamin b12 binds with an intrinstic factor secreted by the gastric mucosa
• vitamin A binds with retinol-bonding protein before it is absorbed
