Question

which protein type helps cells stick together or attach to the extracellular matrix? *
transport protein
adhesion protein
recognition protein
receptor protein

which protein allows your immune system to distinguish “self” cells from “invader” cells? *
receptor protein
transport protein
recognition protein
adhesion protein

Explanation:

Adhesion proteins facilitate cell - cell adhesion or cell - extracellular matrix attachment. Recognition proteins, like major histocompatibility complex (MHC) proteins, allow the immune system to distinguish self from non - self.

Answer:

1. B. Adhesion protein
2. C. Recognition protein
