It is when the cell engulfs a particle. Once the particle is engulfed it lets it go into the cell forming a vacuole.
it is active because it requires energy
active transport
It is when the cell engulfs a particle. Once the particle is engulfed it lets it go into the cell forming a vacuole.
Bulk transport of commercial items requires commercially licensed trucks driven by license professionals. 3PL and transport companies are known for their ability to bulk transport items across states and even countries.
exocytosis which is when cells absorb materials from outside the cell by engulfing it with their cell membrane
Engulfing means totally enclosing.
Engulfing is to sweep over something. Surround something, or completely cover it.
A boat being surrounded by water is a great example of engulfing.
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. :)
Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.
During phagocytosis, the phagocyte is involved with engulfing a smaller particle of organism (or another cell). There is no passive or active transport as such. The process involved enveloping the smaller particle with the cell membrane of the host and bringing it into its interior. There is no diffusion or related passive process involved.
