What is the transport of substances from the outside to the inside of a cell by a vesicle?
Vesicular active transport

What is the transport of substances from outside to the inside of a cell by a vesicle called?
Vesicular active transport
What transport of substances from the outside to the inside of a cell by a vesicle called?
The process of transporting substances from the outside to the inside of a cell using a vesicle is called endocytosis. Endocytosis includes phagocytosis (engulfing solid particles), pinocytosis (engulfing liquid or small particles), and receptor-mediated endocytosis (specific molecules binding to receptors on the cell membrane).
What is an analogy for pinocytotic vesicle?
A pinocytotic vesicle can be compared to a small "bubble" that forms inside a cell to transport liquids or small molecules into the cell. Just like how a bubble can encapsulate and transport something in the air or water, a pinocytotic vesicle encapsulates and transports substances inside a cell.
What is the transport of a substances from the outside to the inside of a cell by a vesicles called?
Vesicular active transport
What is an analogy for a transport vesicle?
A good analogy for a transport vesicle would be a passenger vehicle, like a bus. The analogy could work in two ways: molecules are to a transport vesicle as passengers are to a bus, or a transport vesicle is to a cell as a bus is to a city.
In active transport carrier proteins do what?
They help transfer substances from the outside of the cell membrane to the inside.
Which process is occurring when a vesicle fuses with the cell membrane and releases its contents inside of the cell?
The process that occurs when a vesicle fuses with the cell membrane and releases its contents inside the cell is called exocytosis. Exocytosis is a form of active transport where the vesicle membrane merges with the cell membrane, allowing the vesicle contents to be released into the extracellular space or inside the cell.
How is endocytosis different from exocytosis in terms of cellular processes?
Endocytosis is the process by which cells take in substances from outside the cell by engulfing them in a vesicle, while exocytosis is the process by which cells release substances from inside the cell by fusing vesicles with the cell membrane. In summary, endocytosis brings substances into the cell, while exocytosis releases substances out of the cell.
What does a vesicle do in a cell?
Vesicle holds water for the cell
Based on diffusion what will happen to the substances inside and outside of the cell?
Substances will move from an area of high concentration to an area of low concentration in order to achieve equilibrium. Inside the cell, substances will diffuse out if the concentration outside is higher, and substances will diffuse in if the concentration outside is lower, until equilibrium is reached.
When a cell takes in substances through endocytosis the outside of the cell membrane becomes the inside of the vesicle. what might this suggest about the structure of the cell membrane?
This suggests that the cell membrane is a dynamic structure that can bend and invaginate to form vesicles during endocytosis. It is composed of a phospholipid bilayer with hydrophilic heads facing the aqueous environments (inside and outside) and hydrophobic tails sandwiched in between. The ability of the cell membrane to undergo endocytosis implies its flexibility and capability to change shape.
What allows a cell to stockpile substances in far greater concentration that they occur outside the cell?
Cells are able to stockpile substances in high concentrations through active transport mechanisms, such as pumps or transporters, which use energy to move molecules against their concentration gradient. These mechanisms allow cells to accumulate substances in greater amounts than their surrounding environment.
