PLEASE answer them all I really need help! for Biochemistry

The acetylcholine receptor is an example of a -gated channel. voltage signal ligand all of the above none of the above EGF signaling is terminated by the action of phosphatases and the hydrolysis of by Ras. cAMP ATP ADP GTP GDP Adenylate cyclase is activated by: binding to the GDP bound form of G_alpha s. binding to the G_beta y complex. direct interactions with the beta-adrenergic receptor. cAMP binding. binding to the GTP bound form of G_alpha s.

Explanation / Answer

C Ligand gated channels, Acetylcholine receptors are example of ligand gated channels, in which Na+ K+ , Ca+2 pass through channels when ligand binded (chemical messenger) Eg: Nicotinic acetyl choline receptors D GTP, Ras protein control cellular signalling of the growth, for activation GTP hydrolysis is essential. E binding to the GTP bound form of G protein coupled receptor(beta andregenic recptor) such that activation of adenyl cyclase enzyme invovles in signal transuction.
