Gabriela is sick with a bad cold. her immune system is defending her body against the invading virus. the first line of defense is cells called macrophages, which attack viral particles. the cells eliminate viral particles in a process called endocytosis. arrange the steps of endocytosis in order of what occurs. 1. cell surface receptors bind to the viral particle. 2. lysosome within the cell encloses the viral particle. 3. viral particle is surrounded by the cell membrane. 4. cell membrane curves around toward the cell's interior. 5. lysosome's digestive enzymes destroy the viral particle. 6. cell recognizes the viral particle as foreign material. 1. 2. 3. 4. 5. 6.
