Endocytosis

[Ray25]

Hey everyone!

I'm a beginner in biology and I have a question with regards to endocytosis.

I want to make sure that the red-colored oval features that are depicted in the below endocytosis image are receptors binding with molecutes and nothing else.

I would really appreciate it if someone could confirm this or, if I'm wrong, let me know what those features represent.

Thanks in advance!
