Suppose a white blood cell destroys invading bacteria by phagocytosis. Which statement best describes this process?

Question

a
The white blood cells are using active transport, and therefore are using energy.
b
The white blood cells are using osmosis and therefore are using energy.
c
The white blood cells are using diffusion and therefore are not using energy.
d
The white blood cells are using passive transport and therefore are not using energy.

Answer 1

The best statement to describe the process of phagocytosis by white blood cells is:

a. The white blood cells are using active transport, and therefore are using energy.

Phagocytosis is a type of active transport where cells engulf large particles, such as bacteria. This process requires energy in the form of ATP because it involves the rearrangement of the cytoskeleton and membrane to engulf the material.
