Actin filaments
How does the extracellular matrix (ECM) affect the metabolic activities of cells?
It alters the metabolic activities of cells
What role does the extracellular matrix (ECM) play in the interaction of cells with other cells?

Study Notes
Extracellular Matrix (ECM)
- ECM consists of various components, but NOT a specific one mentioned in the text (yet to be identified)
- ECM affects the metabolic activities of cells by influencing their behavior, differentiation, and survival
- ECM plays a crucial role in the interaction of cells with other cells, facilitating cell signaling, adhesion, and communication
- ECM provides support against forces by acting as a mechanical barrier, resisting compression, tension, and shear stress, and maintaining tissue structure and organization
This quiz covers the composition and functions of the extracellular matrix (ECM), including the amorphous ground substance containing glycosaminoglycans (GAGs), proteoglycans, and glycoproteins, as well as the fibers. It also explores the impact of the ECM on the metabolic activities of cells.
