Question
Describe what happens to fried chicken after you eat it and it passes through your body. Remember that this chicken will have fat, proteins, and carbohydrates.
1. what organs will it pass through
2. modes of breakdown(mechanical, Chemical*, other [hint: its bacteria, mention the role of bacteria]
3. what chemicals/enzymes are involved in the breakdown and which organ makes them.
4. how the food moves through the GI tract
5. where each nutrient are obsorbed (fat, carb, protein)
Please limit discussion to bile, hydrochloric acid, trypsin, pepsin, amylase, and Lipase
Explanation / Answer
Ans. 1. They pass through mouth, stomach and then small intestine.
2. They are breakdown by the enzymes present in mouth, stomach and the small intestine. These enzymes are secreted by the various glands in the body.
3. Enzymes involved in the breakdown and which organs makes them.
Fats-its digestion begins when tongue secretes fat splitting enzyme lingual lipase. Then it passes to the stomach where gastric lipases are secreted. Together they emsulsifies the fat by breaking down the large fat globules into smaller ones.
Most fat digestion take place in the small intestine where emulsification continues with the help of enzyme bile acids which is secreted by the gall bladder, where they are stored after being produced by the liver.
Pancreatic enzymes secreted by the pancreas then spilts the triglycerides into diglycerides, monoglycerides and free fatty acids.
Proteins :- the digestion of protein begins in the stomach where the mixture of enzymes pepsin and HCL are secreted that denatures the proteins within the food. Pepsin breaks the protein into smaller polypeptides and their constituent amino acids.
When it enters the small intestine, trypsin and chymotrypsin breakdown the large protein into smaller peptides, a process called proteolysis.
Carbohydrates:- its digestion begins in the mouth with the help of the enzyme salivary amylase secreted by salivary glands. Then it continues in the duodenum with the action of enzyme pancreatic amylase secreted by the pancreas and it breakdown the polysaccharides into monosaccharides.
4. They moves through the GI tract with the help of enzymes secreted by the small intestine, mentioned in the above answer.
5. Fats after being digested by the small intestine, their smaller fat components are absorbed by the cells of the intestinal wall.
Proteins after being finally digested by small intestine, they are transported across the apical surface of the intestinal mucosa with the help of sodium amino acid transporters.
Carbohydrates also after being digested absorbed by the epithelium of the small intestine.
