Exocytosis
Exocytosis is a biological process where a cell expels substances. It works like this: tiny bubbles called vesicles carry materials, such as hormones or waste, to the cell's outer membrane. When the vesicle membrane fuses with the cell membrane, it opens up and releases the contents outside the cell. This process is essential for communication between cells and for eliminating waste. Exocytosis plays a critical role in various functions, such as releasing neurotransmitters in the nervous system or secreting digestive enzymes. It helps maintain the cell's internal environment and supports overall bodily functions.
