Lysosomes would play the most direct role in eliminating bacteria engulfed by a phagocytic white blood cell.
- An organelle of a cell that is membrane-bound and houses digestive enzymes is called a lysosome. Numerous cell processes involve lysosomes. They disassemble extra or worn-out cell components. They could be utilized to eliminate invasive bacteria and viruses.
- lysosome, a subcellular organelle that is present in almost all eukaryotic cells (cells with a distinct nucleus) and is in charge of breaking down macromolecules, defunct cell components, and microbes.
- Each lysosome is enclosed by a membrane that uses a proton pump to keep the interior of each lysosome acidic. Numerous hydrolytic enzymes (acid hydrolases) are found in lysosomes and break down macromolecules such nucleic acids, proteins, and polysaccharides.
- Only the acidic interior of the lysosome is where these enzymes are active.
Therefore, lysosome is the correct answer.
