Describe how to protein is digested after you ate a steak of dinner that contained fat and protein?

Answer 1

After consuming a steak, protein digestion begins in the stomach, where gastric juices, including hydrochloric acid and pepsin, break down proteins into smaller peptides. As the partially digested food moves into the small intestine, pancreatic enzymes like trypsin and chymotrypsin further cleave peptides into amino acids. Simultaneously, bile from the liver emulsifies fats, allowing lipases to break them down into fatty acids and glycerol. The resulting amino acids and fatty acids are then absorbed through the intestinal walls into the bloodstream for use by the body.
