Question 1

A milk-curdling enzyme found in the stomach of ruminant mammals is ____________.

Accepted Answer

rennin

Question 2

Outline the process of digestion of carbohydrates.

Accepted Answer

The process of digestion of carbohydrates begins in the mouth, where the enzyme amylase breaks down complex carbohydrates into simpler sugars such as glucose. The food then travels to the stomach, where it is mixed with gastric juices that further break down the carbohydrates.

Next, the food moves to the small intestine, where the pancreas releases more enzymes such as amylase, maltase, and sucrase to continue breaking down the carbohydrates into monosaccharides. These monosaccharides are then absorbed into the bloodstream and transported to the liver.

In the liver, the monosaccharides are either used for immediate energy or converted into glycogen for storage. Any excess glucose is converted into fat for long-term energy storage.

Overall, the process of carbohydrate digestion involves the breakdown of complex carbohydrates into simpler sugars, absorption into the bloodstream, and utilization or storage of the resulting monosaccharides for energy.

Question 3

Outline the process of digestion of fats.

Accepted Answer

The process of digestion of fats begins in the mouth, where the enzyme lingual lipase starts breaking down some of the fats in the food. However, the majority of fat digestion occurs in the small intestine.

When the food reaches the small intestine, the gallbladder releases bile into the intestine. Bile helps to emulsify the fats, breaking them down into smaller droplets that can be more easily digested by enzymes.

The pancreas also releases enzymes, such as lipase, which further break down the fats into fatty acids and glycerol. These smaller molecules can then be absorbed through the walls of the small intestine and into the bloodstream.

Once in the bloodstream, the fatty acids and glycerol are transported to various tissues in the body, where they can be used for energy or stored for later use. Any remaining waste products are eventually excreted from the body.
