Question

Highlight the contribution of Succus entericus in the digestion of (a) proteins and (b) disaccharides.

✓

Answer

Proteins:

Succus entericus contains enzymes enterokinase and dipeptidases for protein digestion.
Enterokinase activates trypsinogen into its active form, trypsin and initiates protein digestion in the intestine.
Dipeptidases catalyses the breakdown of dipeptides into the constituent amino acids.

Disaccharides:

Maltase, sucrase and lactase are the enzymes to digest the disaccharides into their component monosaccharides; their actions are as follows:

$\text{Maltose}\xrightarrow{\text{Maltase}}\text{Gluecose}+\text{Gluecose}$
$\text{Sucrose}\xrightarrow{\text{Surcase}}\text{Gluecose}+\text{Fructose}$
$\text{Lactose}\xrightarrow{\text{Lactase}}\text{Gluecose}+\text{Gluecose}$
