| Question | Answer |
|---|---|
| What are the Enzymes of Carbohydrate Digestion? | Salivary amylase (ptyalin), Pancreatic amylase, Maltase, Sucrase, Lactase... PLASMAS. |
| What are the Enzymes of Protein Digestion? | Pepsin, Trypsin, Chymotrypsin, Carboxypeptidase, Aminopeptidase, Dipeptidases, Enterokinase... ACCEPT'D |
| Salivary Amylase (ptyalin). Site of Production? Site of function? Action? | Salivary Glands. Mouth. Starch ->Maltose. |
| Pancreatic amylase. Site of Production? Site of function? Action? | Pancreas. Small Intestine. Starch -> Maltose. |
| Maltase. Site of Production? Site of function? Action? | Intestinal Glands. Small Intestine. Maltose -> 2 Glucose. |
| Sucrase. Site of Production? Site of function? Action? | Intestinal Glands. Small Intestine. Sucrose -> Glucose + Fructose |
| Lactase. Site of Production? Site of function? Action? | Intestinal Glands. Small Intestine. Lactose -> Glucose + Galactose. |
| Pepsin. Site of Production? Site of function? Action? | Gastric glands (chief cells). Stomach. Hydrolyzes specific peptide bonds. |
| Trypsin. Site of Production? Site of function? Action? | Pancreas. Small Intestine. Hydrolyzes specific peptide bonds. Converts chymotrypsinogen to chymotrypsin. |
| Chymotrypsin. Site of Production? Site of function? Action? | Pancreas. Small Intestine. Hydrolyzes specific peptide bonds. |
| Carboxypeptidase. Site of Production? Site of function? Action? | Pancreas. Small Intestine. Hydrolyzes terminal peptide bond at carboxyl |
| Aminopeptidase. Site of Production? Site of function? Action? | Intestinal Glands. Small Intestine. Hydrolyzes terminal peptide bond at amino. |
| Dipeptidase. Site of Production? Site of function? Action? | Intestinal Glands. Small Intestine. Hydrolyzes pair of amino acids. |
| Enterokinase. Site of Production? Site of function? Action? | Intestinal Glands. Small Intestine. Converts trypsinogen to trypsin. |
| What is the fat emulsifier involved in lipid digestion? Where is it made? Where does it function? Where is it stored? Hint: Not a hormone. | Bile. Liver. Small intestine. Gall Bladder. |
| What is the enzyme that hydrolyzes lipids? Where is it made? Where does it function? | Lipase. Pancreas. Small Intestine. |
| What is Pancreatic Juice? Where does it come from? How is this triggered? | Clear alkaline (contains bicarbonate) digestive fluid secreted by the Pancreas which helps neutralize the acidic chyme. Triggered by Secretin and CCK (cholecystokinin). |
