The bacterial cell itself contains receptors and these receptors are shown in purple. When these receptors bind to our cell membrane receptors, that will signal the process of imagination. So we have the protrusion taking place and that is pushed into our cell, forming our phagosome. So, unlike penocytosis, in which we have a random type of process in which it's not specific this is more specific and it involves these protein receptors found on the cell membrane as well as on that object in this case, our bacterial cell. Now, the final type of endocytotic process we're going to discuss is receptor mediated endocytosis. So this is basically the most specific type of endocytotic process and it involves the ingestion of macromolecules such as sugars and hormones and we also have the binding to our receptor proteins.
