The order of events that is most accurate for activation of G protein coupled receptors signaling pathways is: Hormone binds GPCR, GPCR binds with G protein, G protein loses GDP and gains GTP, G-protein alpha subunit activates intracellular proteins.

Why is this correct?

This series of events stands as the most precise and widely acknowledged process for initiating G-protein-coupled receptor (GPCR) signaling pathways according to contemporary scientific comprehension.

It is extensively documented and serves as the standard pathway for GPCR signaling, holding significant importance in diverse cellular functions and physiological responses.

Complete question:
Which of the following order of events is most accurate for activation of G-protein- coupled receptor (GPCR) signaling pathways?

Hormone binds GPCR, GPCR binds with G protein, G-protein alpha subunit activates intracellular proteins, G protein loses GDP and gains GTP

Hormone binds GPCR, G protein loses GDP and gains GTP, G-protein alpha subunit activates intracellular proteins, GPCR binds with G protein

GPCR binds with G protein, hormone binds GPCR, G protein loses GDP and gains GTP, G- protein alpha subunit activates intracellular proteins

Hormone binds GPCR, G protein loses GDP and gains GTP, GPCR binds with G protein, G- protein alpha subunit activates intracellular proteins
