Question

What is the ultimate fate of the digested chicken and rice? What was the initial biological structure of the nutritional components first consumed (example proteins breaking down to their simpler components) and what are the resulting products resulting from digestion that are now ready and available for use by the body for energy and homeostasis?

Answer 1

1) Fate of chicken

Chicken is mainly protein .The proteins we eat are large, globular molecules made up of smaller molecules called amino acids.

the amino acids are bonded with peptide bonds

Chewing of protein in mounth increases the surface area for better action of enzymes

In stomach : The acidic environment denatures, or unfolds, the proteins so digestive enzymes can act on it properly. Converts protein to peptides

In small intestine : The enzymes present here work on the peptides, systematically breaking them down into even smaller peptides and then snipping off the amino acids one by one.

Finally these small amino acids are being absrobed by our body

2) Fate of rice :

Rice mainly consists of carbohydrates

The carbohydrate is digested in mouth (30%) and then in the stomache and intestine

The carbohydrates are made of small glucose molecules

The final product is glucose in digestion of carbohydrates

Glucose are linked with glycosidic linkage between them
