Question: A bacterium engulfed by a white blood cell through phagocytosis will be digested by enzymes contained in?

A bacterium engulfed by a white blood cell through phagocytosis will be digested by enzymes contained in lysosomes.

Lysosomes are organelles that contain digestive enzymes that can break down a variety of molecules, including proteins, carbohydrates, lipids, and nucleic acids. When a white blood cell engulfs a bacterium through phagocytosis, the bacterium is enclosed in a vesicle called a phagosome. The phagosome then fuses with a lysosome, forming a phagolysosome. The enzymes in the lysosome then break down the bacterium.

Lysosomes are essential for the immune system to function properly. They help white blood cells to destroy bacteria, viruses, and other foreign invaders. Lysosomes also play a role in cell turnover and remodeling.

Here is a simplified explanation of what happens to a bacterium after it is engulfed by a white blood cell through phagocytosis:

1. The white blood cell extends its pseudopodia (finger-like projections) and surrounds the bacterium.
2. The pseudopodia fuse together, forming a phagosome that encloses the bacterium.
3. The phagosome fuses with a lysosome, forming a phagolysosome.
4. The enzymes in the lysosome break down the bacterium.
5. The digested bacterium is released into the cytoplasm of the white blood cell.
6. The white blood cell then uses the nutrients from the digested bacterium to produce energy and repair itself.

Phagocytosis is an essential process for the immune system to defend the body against infection. It is also important for other processes, such as cell turnover and remodeling.
