Question

Explain digestion and absorption of carbohydrates

Answer 1

Digestion:It is digested by bile juices and converted into simpler sugars.
Absorption:It absorbed in the small intestine by the villi present inside the small intestine.

Answer 2

• The digestion of the proteins begin in the stomach where it is acted upon by the proteolytic enzyme of the stomach, pepsin. Pepsin converts proteins into proteoses and peptones (peptides).
• Proteins, proteoses and peptons in the chyme reaching the intestine are acted upon by the proteolytic enzymes (trypsin, chemotrypsin, carboxypeptidases) of the pancreatic juice and are converted into dipeptides.
• The enzymes in the succus entericus acts on the end product of the above reaction to form the simple absorbable forms.
• Dipeptidases present in the succus entericus converts the dipeptides into amino acids. Amino acids thus formed are absorbed in the jejunum and ileum regions of the small intestine.
