Phagocytosis is the method the cell uses to engulf food right ?

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.

What this person has said is true and quite often each molecule that is engulfed has its own unique proteins which help for future identification. Say for example you catch a bacterial infection. Your white blood cells engulf the bacteria and make a record of the proteins that the certain type of bacteria uses as receptors so then it can fight it better and faster in the future.

Hope this explains it😊

Phages are symbitoes… not of our genome. They patrol and eat infected cells... or even suspicious cells. It is phages which give you the sore throat. They are ruthless but also help control an infection.

Don't call it food, they are pathogens, bacteria or foreign objects.

Correct... it is attacked, consumed and used if possible. Our body treats both food and foreign bodies the same. We do however carry a host of symbiotes we do recognise and don't attack. The process by which they are recognised is still uncertain.
