G Proteins 2 Termination of Response

The video explores the mechanisms for terminating the activity of the G protein system. It covers four main methods: using phosphodiesterase to hydrolyze cyclic AMP, employing phosphatases to deactivate enzymes, utilizing nucleotide exchange factors to convert GTP to GDP, and the role of beta arrestin in receptor desensitization. Each method is explained in detail, highlighting the biochemical processes involved and their impact on cellular responses.
