A G-protein coupled receptor (GPCR) is a type of transmembrane receptor that detects molecules outside the cell and activates internal signal transduction pathways and cellular responses.

A synapse is the junction between two neurons where neurotransmitters are released to facilitate communication.

Yes, plant cells communicate using hormones, which are signaling molecules that regulate various physiological processes.

The main steps are Reception (detecting the signal), Transduction (converting the signal), Amplification (increasing the signal strength), and Response (the cellular action resulting from the signal).

Ligand-operated ion channels are proteins that open or close in response to the binding of a chemical messenger (ligand), allowing ions to flow across the membrane.

Neurotransmitters are chemical messengers that transmit signals across a synapse from one neuron to another, influencing various functions in the nervous system.

Signal amplification is the process by which a small number of signaling molecules can produce a large response in the target cell.

Paracrine signaling involves the release of signaling molecules that affect nearby cells, while endocrine signaling involves hormones released into the bloodstream to affect distant cells.

A receptor tyrosine kinase is a type of cell surface receptor that, when bound by a ligand, activates its intrinsic kinase activity, leading to phosphorylation of tyrosine residues on itself and other proteins.

G-proteins act as molecular switches that relay signals from activated receptors to target proteins inside the cell, influencing various cellular responses.
