Question

A student ate a steak for dinner hich contains proteins ,how proteins are digested

Answer 1

When a student eats a steak for dinner which contains proteins, the proteins are digested in several stages. The first stage of protein digestion occurs in the stomach, where the proteins are broken down into smaller pieces by the action of hydrochloric acid and an enzyme called pepsin. The resulting mixture of partially digested proteins, called chyme, then moves into the small intestine.

In the small intestine, the pancreas secretes enzymes called proteases, which continue to break down the proteins into smaller peptides. These peptides are then further broken down by enzymes called peptidases, which are produced by the lining of the small intestine. The final products of protein digestion are amino acids, which can be absorbed into the bloodstream and transported to the liver for processing and distribution to other parts of the body.

Overall, the digestion of proteins involves the action of several different enzymes and takes place over a period of several hours.

Answer 2

Proteins are digested in several stages. The process begins in the stomach, where the acidic environment and enzymes break down the proteins into smaller peptides. The stomach produces an enzyme called pepsin, which is activated by the acidic environment, and it breaks down the peptide bonds between amino acids in proteins.

After leaving the stomach, the partially digested proteins enter the small intestine, where additional enzymes are secreted by the pancreas and small intestine. These enzymes break down the peptides into smaller peptides and individual amino acids. Once the peptides are broken down into individual amino acids, they can be absorbed into the bloodstream and transported to cells throughout the body.

The amino acids are then used by cells to build new proteins or for other metabolic processes. Any excess amino acids are converted into other molecules or are excreted from the body.
