THORAX ABDOMEN AND PELVIS

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. The sucrase enzyme invertase, which occurs more commonly in plants, also hydrolyzes sucrose but by a different mechanism.

Detailed explanation-3: -Sucrase and isomaltase are involved in the digestion of sugar and starches. 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.
