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? a. cellular response
b. second messenger action
c. signal amplification
d. signal detection

c. signal amplification

Explanation:

The uncoupling of the G-protein and inhibiting of the signal amplification are the two affects of the pertusis toxin. It is released by the bacteria called Bordetella pertusis. The G-proteins are affected by the action of pertusis toxin. The production to the excess level of cAMP due to the conversion of ATP into cAMP the ribosylation of the ADP molecules occurs due to pertusis toxin. This leads to the damage of G-proteins.

if the hares very faster than they are now, and thus the lynx's hunting success rate drops because it will be harder to catch them, the rate that will change will be the pray-rate. the pray-rate will change because more hares will be able to survive, thus more individuals for reproduction, so the end result will be increasing population of hares.

the predator-rate will remain pretty much the same because there will be more than enough pray, but the hunting success rate is stagnant.
