I"m having actually trouble expertise what the use of "total Rac" is below. The answer states that it is essential to understand if the complete amount of Rac is affected by the strain provided. The figure mirrors that total Rac is the very same regardless of the therapy though, so how does it let us recognize if VopC affected Rac expression levels?
Okay, so you knocked out VopC. What if VopC is co-expressed individually through Rac? In various other words, say VopC and Rac both act on the exact same substprice and also both have to be tright here for there to be any type of valuable outcome. If VopC is suddenly knocked out, you"d also suppose Rac to be down-regulated in that case bereason the cell has no require for Rac to be around without VopC too. So in that instance, you wouldn"t check out any type of GTP-Rac at all yet it wouldn"t be due to VopC activating Rac. It"d be a totally independent occasion.

You are watching: Why was the total amount of rac measured in experiment 2?


Okay, so you knocked out VopC. What if VopC is co-expressed independently with Rac? In other words, say VopC and Rac both act on the very same substprice and also both have to be tbelow for tbelow to be any type of beneficial result. If VopC is all of a sudden knocked out, you"d likewise expect Rac to be down-regulated in that case bereason the cell has actually no require for Rac to be roughly without VopC also. So in that situation, you wouldn"t watch any type of GTP-Rac at all but it wouldn"t be because of VopC activating Rac. It"d be a completely independent event.
So based upon the results, given that full Rac levels didn"t adjust regardmuch less of VopC activation/inactivation, this shows that Rac expression isn"t dependent on VopC? And in the instances where there is GTP-Rac, we watch that each instance likewise has VopC present, however considering that the total Rac is unadjusted, we can just conclude that VopC activates Rac -> GTP-Rac, but does not induce Rac expression? Just trying to check out if this is the correct reasoning.
So based on the outcomes, given that full Rac levels didn"t adjust regardless of VopC activation/inactivation, this suggests that Rac expression isn"t dependent on VopC? And in the situations where tbelow is GTP-Rac, we watch that each situation likewise has VopC existing, but considering that the complete Rac is unreadjusted, we have the right to just conclude that VopC activates Rac -> GTP-Rac, yet doesn"t induce Rac expression? Just trying to watch if this is the correct thinking.
Yes. If they were looking at levels of Rac activation by VopC, they wouldn"t want a cobeginning variable bring about the observed differences in Rac activation. If for some factor VopC brought about a distinction in expression levels of Rac, then a portion of the observed difference in Rac activity would be attributable to distinctions in Rac expression levels. By confirming that Rac expression does not adjust, we"ve eliminated the possibility of this constarting variable contributing to the observed differences in Rac activity level.
