______ are essential for cell communication and are sorted by their ______ and ______.

Membrane receptors are divided into three types: ion channel-linked receptors, --______ receptors, and enzyme-linked receptors.

Ion channel-linked receptors regulate the ______ of ions across the cell membrane upon ______ attachment.

GPCRs trigger ______-proteins inside the cell, influencing different ______ ______.

Enzyme-linked receptors have an extracellular domain for ligand binding and an intracellular part with ______ ______ that often functions as kinases.

Intracellular receptors, like those for ______ hormones, bind to ______ ligands and can alter gene expression by directly interacting with ______.

Key components in signal transduction cascade

Role of second messengers in signal amplification

Consequences of signal transduction on cellular functions

Bacteria use ______ ______ to sense population density and control group behaviors like biofilm formation.

In ______, signaling molecules may be released into the space outside cells or passed through direct interactions between cells.

The nervous system utilizes ______ signaling, allowing neurons to quickly communicate with other neurons or target cells.

This precise and dynamic communication is vital for directing developmental processes, ______ responses, and sustaining physiological equilibrium.
