Question

Describe the process of digestion of protan in stomach

Answer 1

In the human digestive system, food enters the mouth and mechanical digestion of the food starts by the action of mastication(chewing), a form of mechanical digestion, and the wetting contact of saliva. Saliva, a liquid secreted by the salivary glands, contains salivary amylase, an enzyme which starts the digestion of starch in the food; the saliva also contains mucus, which lubricates the food, and hydrogen carbonate, which provides the ideal conditions of pH (alkaline) for amylase to work. After undergoing mastication and starch digestion, the food will be in the form of a small, round slurry mass called a bolus. It will then travel down the esophagus and into the stomach by the action of peristalsis. Gastric juice in the stomach starts protein digestion. Gastric juice mainly contains hydrochloric acid and pepsin. It also contains rennin in case of infants and toddlers. As the first two chemicals may damage the stomach wall, mucus is secreted by the stomach, providing a slimy layer that acts as a shield against the damaging effects of the chemicals. At the same time protein digestion is occurring, mechanical mixing occurs by peristalsis, which is waves of muscular contractions that move along the stomach wall. This allows the mass of food to further mix with the digestive enzymes. I HOPE IT HELPFUL FOR YOU. PLEASE MAKE MY ANSWER BRILLIANT.

✨The digestion of proteins begins in the stomach and is completed in the small intestine.

✨The digestive juice secreted in the gastric glands present on the stomach walls is called gastric juice.

✨The food that enters the stomach becomes acidic on mixing with this gastric juice.

✨The main components of gastric juice are hydrochloric acid, pepsinogen, mucus, and rennin.

✨Hydrochloric acid dissolves the bits of food and creates an acidic medium so that pepsinogen is converted into pepsin.

✨Pepsin is a proteolytic enzyme.

✨It is secreted in its inactive form called pepsinogen, which then gets activated by HCL.

✨The activated pepsin then converts proteins into proteases and peptides.

✨Rennin is a proteolytic enzyme, released in an inactive form called prorennin.

✨ Rennin plays an important role in the coagulation of milk.
