Based on what I read, phagocytosis requires the molecule to be engulfed to have proteins that will bind to the receptor proteins on the cell, this prompted me to ask 3 questions:
1-Are the proteins on the molecules to be engulfed the same proteins that are used for identification ? So glycoproteins ?
2-Does the food that the phagocyte engulfs have membrane proteins ?
3-When we say food, what exactly do we mean ?
I believe phagocytosis is the process of which the phagocyte cell (a type of white blood cell) engulfs pathogens such as bacteria etc.
Hope this explains it😊
