The extracellular matrix attached to cells via glycoproteins may then bind to ________ in the plasma membrane.
A) dynein
B) collagen
C) integrins
D) polysaccharides

Question

Quizplus · Accepted Answer

Integrins are transmembrane proteins that connect the extracellular matrix to the cytoskeleton of the cell. They bind to glycoproteins in the extracellular matrix and to intracellular proteins, such as vinculin and talin, which then bind to actin filaments within the cytoskeleton. Dynein is a motor protein that moves along microtubules and is not involved in binding to the extracellular matrix. Collagen is a protein found in the extracellular matrix, but it is not involved in binding to the plasma membrane. Polysaccharides are not typically involved in binding to the extracellular matrix or the plasma membrane.
