NCERT Solutions for Class 11 Biology Chapter 16 - Digestion and Absorption
FAQs on NCERT Solutions for Class 11 Biology Chapter 16 - Digestion And Absorption
1. Explain the Process of Digestion of Protein in the Stomach.
The stomach is the organ where the digestion of protein begins, and the small intestine is the place where it ends. Gastric glands present on the stomach walls secrete digestive juices known as gastric juice. Gastric juice consists of hydrochloric acid, mucus, rennin and pepsinogen. Pepsinogen is converted into pepsin (digestive protein enzymes) by the acidic medium created by hydrochloric acid after dissolving food particles. Then, the activated pepsin converts the proteins into proteases and peptides.
2. Describe the Functions of the Liver.
The liver, the heaviest and largest organ of the human body, does not directly participate in the digestion. It is responsible for secreting bile juice, which is one of the essential juices that helps in the emulsification of fats. Bile is one of the digestive juices that are responsible for breaking down large lipid globules into several small lipid globules.

6. How many layers are there on the walls of the alimentary canal?
There are four layers on the walls of the alimentary canal:
Serosa - It is the outermost layer of the alimentary canal.
Muscularis - It helps in moving and churning the food by the enzymes of digestion.
Sub-Mucosa - It is a supporting pillar of Mucosa. It compromises big blood vessels and nerves with uneven layers of connective tissue.
Mucosa - It is the innermost layer of the alimentary canal. This layer is helpful for absorption and secretion.
7. Describe the process of digestion in the stomach?
The digestion starts in the stomach and it gets completed in the small intestine. The digestive juice secreted by digestive glands which consists of hydrochloric acid, pepsinogen, mucus and rennin. The Proenzyme pepsinogen on exposure to hydrochloric acid converts to an active enzyme called pepsin which is a proteolytic enzyme of the stomach. Pepsin converts proteases into peptones.
