When a cell first takes in a virus, what organelle tries to destroy it? a: glycoprotein b: lysosome c: mitochondria d: nucleus what type of cell engulfs an invading pathogen and displays its antigens? a: a lymphocyte b: a macrophage c: a red blood cell d: a platelet

1. The correct answer is option B, that is, lysosome.  

A lysosome refers to a membrane-bound organelle found in the majority of plant cells and in various animal cells. They are the spherical vesicles, which comprises hydrolytic enzymes, which can dissociate down various kinds of biomolecules. The lysosomes function as the cell's waste disposal system by digesting undesired substances in the cytoplasm, both from obsolete constituents within the cell and from outside the cell.  

2. The correct answer is option B, that is, a macrophage.  

A kind of white blood cell, known as macrophages, engulfs and digests foreign substances, cellular debris, cancer cells, and microbes by a process called phagocytosis. A macrophage will demonstrate the antigen of the pathogen to the corresponding helper T cell after digesting a pathogen.
