Structural View of Biology

Infrastructure and Communication Cells require a complex infrastructure of molecules for support and communication. Our bodies contain about 10 trillion cells, which must cooperate for the good of the entire body. This requires a complex infrastructure to organize them into tissues and organs, and a complex network of signals to coordinate their action. Click on any of the sub-categories below to explore further.

Structural Proteins

Huge proteins are built to support cells, tissues and organs.

Communication with Hormones

Hormones are used to communicate over long distances throughout the body.

Signaling and Transport Across Cell Membranes

Receptors and transporters are used to manage traffic of molecules and information across the waterproof cell membrane.
