It serves as a passageway for particles to permeate the plasma membrane.
2)
It mediates cell-cell and cell-substratum interactions.
3)
It provides mechanical protection for cells.
4)
It binds important regulatory factors that act on the cell surface.
Q 2 ) Which type of proteins are common to a cell's Extracellular Matrix (ECM)?
1)
Laminins
2)
Proteoglycans
3)

Explanation / Answer
1) Option 4 does not support the statement because glycolax doesnot bind important regulatory factors that act on the cell surface.
2) I think Laminins, Fibronectins and collagens are the type of proteins which are common to a extra cellular matrix(ECM).
