What else can I help you with?
Identify the terms endocytosis and exocytose and distinguish between them?
Endocytosis is the process by which cells absorb material by engulfing it with their cell membrane to form a vesicle. Exocytosis is the process by which cells expel material by fusing a vesicle containing the material with the cell membrane, releasing its contents outside the cell. Endocytosis brings materials into the cell, while exocytosis expels materials out of the cell.
What is it called when the movement of a substance into a cell by a vesicle?
endocytosis
What is the process by which the vesicle of a cell transports a substance to the cell surface and then fuses with the membrane to release substance from the cell is called what?
The process by which a vesicle transports a substance to the cell surface and then fuses with the membrane to release the substance from the cell is called exocytosis. During exocytosis, the vesicle membrane merges with the plasma membrane, allowing the contents of the vesicle to be expelled into the extracellular space. This process is essential for various cellular functions, including secretion of hormones, neurotransmitters, and other important molecules.
What happens to vesicle in exocytosis?
The vesicle fuses with the cell membrane, releasing it's contents.
What is the procces by which a substance is released from the cell through a vesicle that transports the substance to the cell surface in then fuses with the membrane to let the substance out?
exocytosis
When a vesicle fuses with the cell membrane to get rid of a particle what happens?
a vesicle does not fuse with the cell membrane. The cell membrane goes through endo- or exocytosis to absorb or eject a substance. In this case, exocytosis occurs, so the cell membrane engulfs the particle, pumps it through the membrane with the help of transport proteins, and then the vesicle breaks off and is gone.
What molecules move with endocytosis and exocytosis as opposed to diffusion or active transport?
The difference is that Active transport engulfs the substance by using the cells membrane. Exocytosis engulfs the substance by engulfing it into a vesicle, then bring it into the cell, and Exocytosis releases he substance from a cell by fusion of a vesicle. :)
What occurs when the plasma membrane surrounds a large substance outside the cell and moves it inside the cell?
The process is called endocytosis, specifically phagocytosis if the large substance is solid or pinocytosis if it is liquid. The plasma membrane engulfs the substance, forming a vesicle, and brings it into the cell.
What process brings food into the cell during active transport?
The process that brings food into the cell during active transport is called endocytosis. This involves the cell membrane engulfing and forming a vesicle around the food particles to bring them into the cell. Once inside the cell, the vesicle fuses with other cellular components for further processing.
When a cell membrane actively surrounds a solid substance and forms a vesicle which moves into the cell this is called what?
This process is known as endocytosis, specifically phagocytosis if the solid substance being engulfed is a large particle or bacterium. Endocytosis involves the cell membrane wrapping around the substance to form a vesicle that is then internalized into the cell.
The movement of a substance into a cell by a vesicle is called?
Phagocytosis if a particle was absorbed. Pinocytosis if a fluid was absorbed.
What is the process in which the cell surrounds and takes in a substance from its environment by forming a vesicle from the plasma membrane?
Respiration ;)
