Fibers of the extracellular matrix are attached to_ plasma membrane:
Correct answer: C. Proteins
- A. Phospholipids
- B. Glycolipids
- C. Proteins
- D. Carbohydrates
Explanation
The correct answer is Proteins. The fibers of the extracellular matrix attach to proteins known as integrins within the plasma membrane. Integrins span the membrane and connect to both extracellular matrix proteins and intracellular cytoskeletal proteins, enabling the cell to transmit signals and maintain its structure. Phospholipids form the bilayer of the membrane but are not directly involved in binding the matrix fibers. Glycolipids, with their role in cell recognition, and Carbohydrates, involved in signaling, do not serve as attachment points for the extracellular matrix.

About Cell Structure and Function
Animal, plant, prokaryotic and eukaryotic cells are compared through their membranes, cell walls, nuclei and cytoplasmic organelles. The work includes the structures and functions of mitochondria, chloroplasts, ribosomes, endoplasmic reticulum, Golgi apparatus and lysosomes, as well as chromosome organization and the distinction between chromatin and chromosomes.
