Signals Between the ECM and the Cytoskeleton May Be Transmitted

Question

Signals between the ECM and the cytoskeleton may be transmitted by
A)fibronectin.
B)proteoglycans.
C)integrins.
D)collagen.
E)middle lamella.

Accepted Answer

Integrins are transmembrane receptors that bind to both the ECM and the cytoskeleton, allowing for the transmission of signals between the two. Fibronectin and collagen are components of the ECM, while proteoglycans and the middle lamella play roles in cell adhesion but do not directly transmit signals between the ECM and cytoskeleton.
