You are consuming a food item that contains carbohydrates, lipids, proteins, nucleic acids, and a substance A stipulated to not be digestible by human enzymes, but digestible by bacterial enzymes into substance B. Discuss where and how each of the five nutrient types will be digested (multiple locations may be required), and how their absorbable components (monosaccharides, fatty acids, amino acids, nucleotides, and substance B) will be absorbed by the body. Include in your response a complete review of the entire digestive system (not just the digestive tract), including all physical structures the food item will encounter, all digestive secretions (including a breakdown of all enzymatic and non-enzymatic components, and their functions) the food item will occur, and the tissue/organ structures responsible for generating those secretions.

Answer :)

Dietary carbohydrate breaks by salivary amylase in mouth. Polysaccharides, dextrins, lactose, sucrose, and maltose degrades to monosaccharides by pancreatic amylase in the small intestine. Monosaccharides absorb by the intestinal lining.

Lipids digestion starts in the small intestine where bile juice emulsify lipids, breaks the lipids into small fat droplets. Pancreatic lipase starts to degrade lipid molecules in the small intestine. Fatty acids and glycerol absorb in the intestinal lining.

Protein digestion starts in the stomach where HCL, and pepsin enzyme breaks proteins into denatured and partially hydrolyzed proteins. After that trypsin, aminopeptidase, chymotrypsin, and carboxypeptidase act on the proteins in the small intestine and convert into small peptides and amino acids. These products absorb by the intestinal lining.

Nucleic acids are break down in the small intestine by Pancreatic ribonuclease and deoxyribonuclease into nucleosides, which are broken down nucleosidases. The final products: nucleic acid bases, phosphoric acid, and pentose absorbs by the intestinal lining.

Substance A digestion occurs in the colon region, where the products are absorbed too.
