1. | Pancreatic amylase → salivary amylase → lipases |
2. | Disaccharidase like maltase → lipases → nucleases |
3. | Salivary amylase → pancreatic amylase → disaccharidases |
4. | Salivary maltase → carboxy peptidase → trypsinogen |
One of the constituents of the pancreatic juice, while poured into the duodenum in humans is:
1. Enterokinase
2. Trypsinogen
3. Chymotrypsin
4. Trypsin
Which one of the following correctly represents the normal adult human dental formula?
1.
2.
3.
4.
Jaundice is a disorder of:
1. Skin and eyes
2. Digestive system
3. Circulatory system
4. Excretory system
If for some reason the parietal cells of the gut epithelium become partially non-functional, what is likely to happen:
1. | The pH of the stomach will fall abruptly |
2. | Steapsin will be more effective |
3. | Proteins will not be adequately hydrolysed by pepsin into proteoses and peptones |
4. | The pancreatic enzymes, and especially trypsin and lipase, will not work efficiently |
Where do certain symbiotic microorganisms typically occur in the human body?
1. Oral lining and tongue surface
2. Vermiform appendix and rectum
3. Duodenum
4. Caecum
1. Duodenum : Triglycerides Monoglycerides
2. Small intestine : starch Disaccharide (maltose)
3. Small intestine : Proteins Amino acids
4. Stomach : Fats Micelles
1. | Gastric juice will be deficient in chymosin |
2. | Gastric juice will be deficient in pepsinogen |
3. | In the absence of HCl secretion, inactive pepsinogen is not converted into the active enzyme pepsin |
4. | Enterokinase will not be released from the duodenal mucosa and so trypsinogen is not converted to trypsin |
A young infant may be feeding entirely on mother's milk, which is white in colour but the stools, which the infant passes out is quite yellowish. What is this yellow colour due to?
1. Intestinal juice
2. Bile pigments passed through bile juice
3. Undigested milk protein casein
4. pancreatic juice poured into the duodenum
