Input: This process can be triggered by molecules like phosphatidylserine. Some organisms try to avoid this process by using a slime layer or fimbriae. Another way to avoid this process is via protein A, which blocks IgG binding and opsonization. After undergoing this process, some organisms use molecules like sulfatides to avoid encountering acidic conditions, while others use proteins such as listeriolysin O or phospholipase A to avoid death by breaking out of the vacuole that they are sequestered in. Pathogens that aren't so lucky are broken down by the cell that performed this process in an oxygen dependent manner. Cells that do this "professionally" include neutrophils, dendritic cells, and macrophages. For 10 points, name this process in which a cell internalizes solid particles.
