Question
Chapter 5.2, Problem 1BC
Summary Introduction
To explain: The reason for the importance of transmembrane protein in the cell-cell binding and cell-matrix binding.
Introduction: The transmembrane proteins traverse from one end of the membrane to the other end. These proteins are embedded inside the phospholipid bilayer and are organized in such a way that their hydrophobic body lies in the middle region while the outer side of the membrane contains polar amino groups.

- Analogs of hemidesmosomes are the focal contact sites, which are also sites where the cell attaches to the extracellular matrix. These junctions are prevalent in fibroblasts but largely absent in epithelial cells. on the other hand, hemidesmosomes are prevalent in epithelial cells but absent in fibroblasts.
