Which of the following Extracellular Matrix ECM components is described as an ECM protein that attaches the ECM to integrins embedded in the plasma membrane?

  • A: Collagen fibers
  • B: Proteoglycan complexes
  • C: Fibronectin
  • D: Microfilaments

Explanation

The diagram annotation and text state: 'Fibronectin is one ECM protein that attaches the ECM to integrins embedded in the plasma membrane.' The text further elaborates: 'Some cells are attached to the ECM by ECM glycoproteins such as fibronectin. Fibronectin and other ECM proteins bind to cell-surface receptor proteins called integrins that are built into the plasma membrane.'
