GENERAL HISTOLOGY

Detailed explanation-1: -Small Intestine produces Peptidases, Sucrase, Lactase and Maltase and acts upon Peptides, Sucrose, Maltose and Lactose and produces Amino acids, Glucose and fructose, Galactose etc. Hence option D is correct.

Detailed explanation-2: -Sucrase is a digestive enzyme that catalyzes the hydrolysis of sucrose to its subunits fructose and glucose. One form, sucrase-isomaltase, is secreted in the small intestine on the brush border.

Detailed explanation-3: -Sucrase is the intestinal enzyme that aids in the breakdown of sucrose (table sugar) into glucose and fructose, which are used by the body as fuel. Isomaltase is one of several enzymes that help digest starches. CSID is also known as genetic sucrase deficiency and congenital sucrose intolerance.

Detailed explanation-4: -The SI gene provides instructions for producing the enzyme sucrase-isomaltase. This enzyme is made in the cells that line the small intestine, where it is involved in breaking down the sugars sucrose (a sugar found in fruits, and also known as table sugar) and maltose (the sugar found in grains).

Detailed explanation-5: -Amylase (made in the mouth and pancreas; breaks down complex carbohydrates) Lipase (made in the pancreas; breaks down fats) Protease (made in the pancreas; breaks down proteins)
