Question

In many cells, the adhesion to the extracellular matrix through integrins causes the activation of kinases in the cytoplasm. This suggests that:
a. integrins promote the activation of signal-transduction pathways.
b. integrins are kinases.
c. extracellular matrix proteins are receptors and integrins are ligands.

Answer 1

Answer: A

Explanation:

Because integrens create adhesion in extracellular matrix by creating a pathway through kinases. By phosphorylation of continous pathway.
