White blood cells specialize in phagocytosis in which they engulf foreign bacterial invaders. Which cellular organelle would you expect to be enriched within these cells? Lysosomes Rough ER Smooth ER Golgi apparatus Explain your answer here:

Solution

Answer: a. lysosomes

Reason:

The bacterial particles inside the WBC with lysosome (engulfing) to from a endolysosome-to-phagosome fusion finally trigger leakage of internal contents into the cytoplasm of phagocytes. These events are followed by activation of mitochondria hyperpolarization -signaling pathway finally result in \"generation of caspase-9 and -3\" as a result apoptosis or cell death
