Which of the following gastric enzymes digests proteins?
Pepsin is a stomach enzyme that serves to digest proteins found in ingested food. Gastric chief cells secrete pepsin as an inactive zymogen called pepsinogen.
Which hormone functions counteract the effect of gastric acid in the small intestine?
Secretin, a digestive hormone secreted by the wall of the upper part of the small intestine (the duodenum) that regulates gastric acid secretion and pH levels in the duodenum.
Which of the following pancreatic enzymes digests proteins?
The enzymes made by the pancreas include: Pancreatic proteases (such as trypsin and chymotrypsin ) – which help to digest proteins. Pancreatic amylase – which helps to digest sugars (carbohydrates). Pancreatic lipase – which helps to digest fat.
Which hormone is stimulated by high levels of dietary fat in the small intestine group of answer choices?
Cholecystokinin is secreted by cells of the upper small intestine. Its secretion is stimulated by the introduction of hydrochloric acid, amino acids, or fatty acids into the stomach or duodenum.
What are the 4 main digestive enzymes?
The pancreas produces the key digestive enzymes of amylase, protease, and lipase.
What organ is the site of initial protein digestion?
Mechanical digestion of protein begins in the mouth and continues in the stomach and small intestine. Chemical digestion of protein begins in the stomach and ends in the small intestine. The body recycles amino acids to make more proteins.
What are the 3 main hormones that regulate digestion?
The five major hormones are: gastrin ( stomach ), secretin ( small intestine ), cholecytokinin (small intestine), gastric inhibitory peptide (small intestine), and motilin (small intestine).
Which hormone stops acid secretion in the stomach?
The hormone somatostatin stops the release of stomach acid.
What are the 3 pancreatic enzymes?
- Lipase. This enzyme works together with bile, which your liver produces, to break down fat in your diet.
- Protease. This enzyme breaks down proteins in your diet.
- Amylase. This enzyme helps break down starches into sugar, which your body can use for energy.
What is the best pancreatic enzyme?
Pancreatic enzyme supplement choices
- Amylase. This class of digestive enzyme is needed to help break down carbohydrates and sugars.
- Lipase. This digestive enzyme category is pivotal to digestion of oils and fats.
- Protease. These digestive enzymes are necessary for the breakdown of proteins.
Which enzyme is present in pancreatic juice for digestion of proteins?
Pancreatic juice is produced by Pancreas and has many enzymes like trypsin, chymotrypsinogen, elastase, carboxypeptidase, pancreatic lipase, nucleases, and amylase. Out of these enzymes, Trypsin is the one that aids in the digestion of Protein.
What is the hunger hormone?
Ghrelin is a hormone that is produced and released mainly by the stomach with small amounts also released by the small intestine, pancreas and brain. Ghrelin has numerous functions. It is termed the ‘hunger hormone’ because it stimulates appetite, increases food intake and promotes fat storage.
What causes CCK release?
The major nutrients that stimulate CCK release are fats and ingested proteins. Of these, the specific meal components that cause CCK release include fatty acids and amino acids. In some species, proteins appear to stimulate CCK secretion by virtue of their ability to inhibit intralumenal trypsin activity (20, 31).
What does secretin do in the digestive system?
Secretin has 3 main functions: regulation of gastric acid, regulation of pancreatic bicarbonate, and osmoregulation. The major physiological actions of secretin are stimulation of pancreatic fluid and bicarbonate secretion. S cells in the small intestine emit secretin.
