What are the pinocytis?

Answer 1

Pinocytosis is a form of endocytosis in which cells engulf liquid substances and small solutes from their environment. This process involves the invagination of the cell membrane, leading to the formation of small vesicles that transport the ingested material into the cell. Often referred to as "cell drinking," pinocytosis is crucial for nutrient uptake and maintaining cellular homeostasis. It is a non-specific process, meaning that it does not selectively target specific substances.
