All know about this ligand is that it As a result, you it to interaon with receptor AU outer cel cell. within the of the thin the nucleus of cell, memberane. D) on the side of the plasma then adds EO B and D are most likely membranes from the cytoplasm, and 43) if one liver cells, separates the portion, glucagon (uses a GPCR) to the isolated cytoplasmic A) will be produced. B) G-proteins will be activated. adenylyl cyclase will be activated.

Explanation / Answer

According to the Chegg guidelines I'll answer the first question when more than one question is posted.

In this case the first two questions in first paper are not visible so I'll answer the question that is visible first that is question 42.

Answer is A) at the outer cell surface.

B) this option is wrong because the molecule is Hydrophillic and we don't know if there are any transporter for to make the ligand enter the cell.

C) this option is also wrong as the same reason above mentioned reason of the plasma membrane being Hydrophobic and ligand being hydrophilic. Because of this reason the ligand can not enter the cell.

D) the option d and B are same only. So if b is wrong then d is also wrong.

A is correct because cell surface receptor have their ligand binding site on the matrix site. And as the ligand is Hydrophillic it can attach to the ligand binding site of matrix side of the receptor.
