: the pertussis toxin was found to interfere with the ligand-binding site in g-protein coupled receptors. at which point in the

cell signaling pathway would this toxin interrupt normal cell signaling

The point at which the toxin would interrupt normal cell signalling in the pathway is the signal amplification. 
This is because of the G-protein uncoupling and inhibition of signal amplification by pertusis toxin. Pertusis toxin released by the bacteria Bordetella pertusis and prevents signal that is amplifying from the protein. The G-protein coordinates the interaction between membrane bound receptor proteins and the effector proteins involved in the intracellular signalling. The toxin promotes the uncoupling of this heterotrimetric protein and also inhibits the amplification thus preventing the interaction of the receptor proteins and the second messengers.

Summarize the nature versus nurture debate, and explain how contemporary theorists view this debate.
Klio2033 [76]

What property of a hormone would allow it to pass unassisted through a plasma membrane?
siniylev [52]

Ans.

Hormones are regulatory substances synthesized by various plants and animals and play role in proper growth, development, and maintain homeostasis. Hormones are released by signalling cells and show their actions after binding to specific receptors present on the surface or inside of the target cell.

Hormones, for which receptors are present inside the cells (in cytosol or nucleus) should be hydrophobic in nature. This is because plasma membrane is made up lipid molecules and small, hydrophobic, uncharged molecules can easily pass through this. For example, cortisol, estrogen, and progesterone hormones are lipid-derivatives and receptors for these hormones are present inside the cells.
