검증된 단계별 안내1
Understand the context: The problem is asking about a process known as 'cell eating'. This is a type of endocytosis where cells engulf large particles or even other cells.
Identify the key term: 'Cell eating' is a common term used to describe phagocytosis, a process where cells, often immune cells like macrophages, ingest large particles or microorganisms.
Differentiate between the options: Phagocytosis involves the engulfing of large particles, receptor-mediated endocytosis involves the specific uptake of molecules based on receptor binding, pinocytosis is the ingestion of liquid into a cell, and exocytosis is the process of vesicles fusing with the plasma membrane to release contents outside the cell.
Focus on phagocytosis: In phagocytosis, the cell membrane extends around the particle, forming a phagosome, which then fuses with a lysosome for digestion.
Conclude with the correct process: Given the description of 'cell eating', phagocytosis is the correct process as it involves the engulfing and internalization of large particles or cells.
