membrane receptors
Membrane receptors are specialized proteins located on the surface of cells. They play a crucial role in cell communication by binding to specific molecules, such as hormones or neurotransmitters. This binding triggers a series of cellular responses, allowing the cell to react to changes in its environment.
These receptors can be classified into different types, including G protein-coupled receptors and ion channel receptors. Each type has a unique mechanism for transmitting signals into the cell. By facilitating communication between cells and their surroundings, membrane receptors are essential for maintaining various physiological processes.
