Question

Which the following descriptions would be an example of phagocytosis?

A) a low-density lipoprotein that becomes internalized by a hepatic cell
B) a macrophage imbibing its surrounding tissue fluid and nutrients
C) choline's reabsorption by a neuron
D) the elimination of a phagolysosome's contents from a neutrophil
E) bacteria that is engulfed by a white blood cell

Answer 1

Phagocytosis is a process where cells, like white blood cells, engulf large particles or microorganisms such as bacteria, which is what happens in option E of the question.

Step-by-step explanation:

An example of phagocytosis would be option E) bacteria that is engulfed by a white blood cell. Phagocytosis is a cellular process where cells, particularly phagocytes, such as macrophages or neutrophils, extend their membrane to enclose large particles or microorganisms like bacteria. Once engulfed, the particle is enclosed within a vesicle called a phagosome which then fuses with a lysosome to form a phagolysosome. The digestive enzymes and acids from the lysosome degrade the pathogen, and the process concludes with the excretion of the debris.
