mhlearnsmart.com an Physlology 14e, Homeostasis: A Framework for Human Physlology Given the cellular negative feedback example shown, select all of the following that would result from taking a drug that inhibits the activity of Enzyme C. Check all that apply. The concentration of intermediate 1 would decrease The concentration of intermediate 1 would increase The activity of Enzyme A would increase. The concentration of intermediate 2 would increase. The concentration of active product would decrease. Do you know the answer? I know It Think so Unsure No idea

Explanation / Answer

Option A is wrong because as this is an example of negative feedback and C is inhibited, the concentration of intermediate 1 would increase rather than decrease.
Option B is correct because as C is inhibited it wouldn't decrease the activity of enzyme A and concentration of intermediate 1 would increase.
Option C is also correct as concentration of A would increase if C is inhibited.
Option D is also correct because concentration of intermediate 2 will also increase if intermediate 1 is increasing.
Option E is also correct because as the drug inhibits the enzyme C and it as C is inhibited, the concentration of active products would decrease.
