Question

digestion of a amoeba

Answer 1

Digestion in amoeba is intracellular taking place within the cell. 

The food taken in remains in a food vacuole or gastric vacuole formed by the cell membrane and small part of the cytoplasm. 

The vacuoles are transported deeper into the cells by cytoplasmic movements. 

Here they fuse with lysosomes that contain enzymes. 

Two enzymes amylase and proteinase have been reported. Thus, amoeba can digest sugars, cellulose and proteins. Fats, however, remain undigested.

The contents of the vacuole become lighter and the outline of the vacuole becomes indefinite indicating that the digestion is complete.

Answer 2

The food vacuole contains digestive enzymes. With the help of digestive enzymes, the engulfed food is digested in the food vacuoles. Two enzymes amylase and proteinase have been reported. Thus amoeba can digest carbohydrates and proteins.
