Question

Which of the following structure produces digestive enzymes?

• A. I, III and V
• B. II, III and V
• C. III, IV, V, and VIII
• D. I, III, V, and VII
• E. II, III, and IV

Answer 1

Answer: (D)

I, III, V, and VII

The main enzyme-producing structures of the human digestive system are Salivary Glands (represented by 1), Stomach (represented by 3), Pancreas (represented by 5) and Small Intestine (represented by 7).

Salivary glands produces Salivary amylase and it acts upon starch to produce maltose.

Stomach produces pepsin which acts upon proteins and produces partly digested proteins.

Pancreas produces proteases (trypsin), lipases and amylases which acts upon proteins and fats and produces Peptides and amino acids, Fatty acids and glycerol and maltose.

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.
