What processes moves substances in the opposite direction of the others - out of the cell?

The process that moves substances out of the cell, in opposition to others that typically bring materials into the cell, is called exocytosis. During exocytosis, vesicles containing substances fuse with the cell membrane, releasing their contents into the extracellular space. This mechanism is essential for processes such as neurotransmitter release and the secretion of hormones. Additionally, it helps maintain cellular homeostasis by expelling waste products.
