Phagocytosis
What endocytosos process bring particle into cell and “cell eating”
Phagocytosis
What endocytosis process does :
Plasma membrane folds in-> extracellular fluid enters cell
“Cell-drinking”
Pinocytosis
The endocytosis process that Molecule bind to receptor on plasma membrane and binds to the receptor ( star molecule)
- plasma membrane folds after binding
- molecule enters cell
Receptor- mediated endocytosis
The process that expells material from the cell, forms vesicle around expelled mateiral
-composed of phsopholipids
-moves toward end of plasma membrane
- fuses with P.M. and components released .
