Question
One type of immune response in humans occurs when a white blood cell engulfs an invader, such as a virus or bacterium. What type of transport is taking place during this process? Select one:a.Diffusionb.Facilitated diffusionc.Exocytosisd.Endocytosis
Solution
The process by which a white blood cell engulfs an invader, such as a virus or bacterium, is known as endocytosis. So, the correct answer is d. Endocytosis.
Here's a step-by-step explanation:
- The white blood cell recognizes the invader as foreign.
- The cell membrane of the white blood cell changes shape to surround the invader.
- The invader is engulfed within a vesicle created by the cell membrane. This process is called endocytosis.
- The vesicle is transported into the cell, where the invader can be destroyed.
So, endocytosis is the type of transport taking place during this immune response.
