Explanation:
Integrins are principal receptors that bind to the extracellular matrix. They act as transmembrane linkers to link extracellular matrix and the actin cytoskeleton
The adhesive activity of integrins is regulated through two ways –
a) Within the cell
b) Out side the cell by extracellular divalent cations i.e Ca2+ or Mg2+. This shows that there is divalent-cation-binding domains in the extracellular part of the α and β subunits which affects both affinity and the specificity of the ligands to which the integrin binds
Answer:
I believe the answer is a.

Isn't that cool? Like all the body functions depend on each other. Without one system, all the others fail. Really cool lol.
