Explain why one cell would have so many different kinds of proteins embedded in the cell membrane

membrane proteins play different roles (for example, transport of nutrients, signaling pathways, etc)

Explanation:

Membrane proteins are key components that form and interact with biological membranes. Thus, membrane proteins can be classified as 1-integral membrane proteins which are components of the cell membrane and 2-transmembrane proteins that penetrate the membrane in one or both sides of the membrane.  These proteins account for different cellular functions. Some functions of membrane proteins include:

- Cell structure (attachment to the extracellular matrix and/or the  cytoskeleton)

- Transport of nutrients and waste products  

- Intercellular interaction between cells.  

- Signaling transduction functions

- Cell recognition (e.g., during innate immune responses)
