I understand why I got this question wrong: the antibiotic treatment would eliminate gut biota and have the same effect of knocking out the GPCR talked about in the passage, leading to weight gain, and thus an increase in adipocyte size.
I want to make sure I understand insulin sensitivity/resistance. So being insulin resistant is unhealthy (diabetes) because your body produces excess insulin to try and pick up glucose, but glucose uptake does not occur at a high enough rate.
So for this question, choice D would be true if, on the graph shown, the left sub column in the left most main column (GPCR 43 knockout, without acetate), would be lower in value than the WT equivalent in the column next to it, thus showing that the lack of GPCR 43 lowers insulin sensitivity because there is less glucose uptake? And this would be the same effect as in the question stem, which talks about the absence of gut microbiota.
