Secretin and cholecystokinin are digestive hormones. These are secreted by
  • Senescent stage
  • Stationary phase
  • Lag phase
  • Exponential phase
Carbohydrate digestion first occurs in the
  • Oesophagus
  • Duodenum
  • Pyloric stomach
  • Ileum
What will happen if the secretion of the parietal cells of the gastric glands is blocked within an inhibitor?
  • Mouth
  • Intestine
  • Stomach
  • None of the above
Bile contribution to digestion is
  • Gastric juice will lack chymosin.
  • In the absence of HCl secretion, inactive pepsinogen is not converted into active enzyme pepsin
  • Enterokinase will not be released from duodenal mucosa, so trypsinogen is not converted to trypsin.
  • Gastric juice will lack pepsinogen
The gastric juice contains
  • Phagocytosis
  • Carbohydrate digestion
  • Emulsification of dietary fats correct
  • Nucleic acid meta bolism
Oxyntic cells secrete
  • Pepsin, Amylase, Trypsin
  • Trypsin, Pepsin, Lipase
  • Trypsin, Pepsin, Rennin
  • Pepsin, Lipase, Rennin
The enzyme pepsin acts in
  • NaOH
  • Pepsin
  • Trypsin
  • HCl
The pancreas produces
  • Acidic medium in stomach
  • Mouth
  • Intestine
  • Acidic medium in the pancreas
Peptic cells secrete
  • Two digestive enzymes and one hormone
  • Three digestive enzymes and no hormone
  • Three digestive enzymes and two hormones
  • Three digestive enzymes and one hormone
Bile secretion is proportional to the concentration of
  • Pepsin
  • HCl
  • Cholecystokinin
  • Gastrin
