Which form of endocytosis involves a receptor?
Receptor-mediated endocytosis is the form of endocytosis that involves specific receptors on the cell membrane binding to ligands for internalization. This process allows for selective uptake of specific molecules into the cell.
How does the cell engulf liquid of small particles of matter?
Phagocytosis (cell eating) - form of endocytosis(folding in of cell membrane to trap material from the outside) ; cell membrane engulfs solid particles by wrapping around itPinocytosis (cell drinking) - form of endocytosis; cell engulfs liquids by sucking it in
What is it called when a part of a cell membrane closes around a molecule to allow the molecule to enter the cell?
This is called endocytosis.
Is the transport of macromolecules into a cell is called endocytosis?
Yes, the transport of macromolecules into a cell is called endocytosis. This process involves the cell membrane folding inward to form a vesicle that engulfs the macromolecules, bringing them into the cell. There are different types of endocytosis, including phagocytosis for large particles and pinocytosis for liquids. Overall, endocytosis is a crucial mechanism for cellular uptake of essential substances.
Phagocytosis is a form of exocytosis?
Phagocytosis is actually a form of endocytosis, not exocytosis. In phagocytosis, a cell engulfs particles or cells by wrapping its cell membrane around them, forming a vesicle inside the cell. Exocytosis, on the other hand, involves the release of substances from a cell by fusion of a vesicle with the cell membrane.

What is the definition Endocytosis?
The official definition of the word endocytosis is "the taking in of matter by a living cell by invagination of its membrane to form a vacuole."
Does the process of endocytosis require energy?
Yes, the process of endocytosis requires energy in the form of ATP to transport molecules into a cell.
What is the definition if endocytosis?
Endocytosis is a cellular process in which cells engulf molecules or particles by wrapping them in a section of the cell membrane to form a vesicle. This allows the cell to take in substances from the extracellular environment. Endocytosis plays a key role in nutrient uptake, cell signaling, and the removal of waste products.
What is it called when a part of a cell membrane closes around a molecule to allow the molecule to enter the cell?
This is called endocytosis.
Why endocytosis found in animal only?
Endocytosis requires the fluidity of the cell membrane. Plant and prokaryotic cells have cell walls, which do not have the fluidity required to form vesicles around materials.
When a cell ingests a solid particle is it called?
Phagocytosis, a form of endocytosis

Does the process of endocytosis require the use of energy?
Yes, the process of endocytosis requires the use of energy in the form of ATP to transport substances into a cell.
Why is the energy expended during endocytosis worth it?
Endocytosis is the bulk transport of materials into a cell, using energy in the form of ATP. It is an active process, and the energy is used to move the membranes around the materials to form the vesicles that are needed, and to move the vesicles into the cell.
