Question

Cite a case of intracellular digestion in humans.

Answer 1

Hint: Digestion is a mechanism by which food is broken down into nutrients. Extracellular digestion takes place outside of the cell. In humans, the digestive tract breaks down food mechanically and chemically so that the intestinal cells can absorb nutrients from the body. Intracellular digestion is taking place inside the cell.

Complete Answer:
- In humans, the digestive tract breaks down food mechanically and chemically, allowing intestinal cells to absorb nutrients from the body. Food is trapped in the gastrovascular cavity of the hydra. Intracellular digestion is taking place within the cell.
- Intracellular digestion can also be a mechanism in which animals that lack the digestive tract carry food products into the cell for the purpose of digestion for nutritional purposes. In many unicellular protozoans, in some molluscs, Cnidaria and Porifera, this form of intracellular digestion occurs.
- Thus the statement for intracellular digestion in humans is that the digestive tract breaks down food mechanically and chemically so that the intestinal cells can consume nutrients in the body.

Additional information:
Lysosomes are closely related to the Golgi apparatus. These membrane-bound organelles are the locations where most intracellular digestion occurs. They emerge from and communicate closely with the Golgi apparatus, and there is a rapid flow of enzyme and membrane components between them.

Note: An incomplete digestive system consists of a single opening digestive cavity. Both the mouth and the anus serve as a single opening. The full digestive system consists of two openings of the digestive tract. One of the openings is the mouth.
