(a) Cell-matrix fusion complex

(b) Cell-matrix adhesion complex

(c) Cell-matrix substitution complex

(d) Cell-matrix addition complex

I got this question in an interview for job.

This question is from Interaction of Cells with Extracellular Matrix topic in chapter Extracellular Matrix and Cell Interactions of Cell Biology

Answer 1

The correct answer is (b) Cell-matrix adhesion complex

Easy explanation: Cell-matrix adhesion complex shortly known as the CMAC is helpful in the attachment of the cell to the extracellular matrix. This is also aided by special proteins called integrins.
