Glucagon has the opposite effect of insulin on liver cells; it accelerates glycogenolysis and suppresses glycogenesis causes a decrease in blood glucose levels • accelerated by insulin suppressed by…arrow_forwardexplain why natural protease inhibitors (peptide extracts from the pancreas of cattle - aprotinin) can also arrest the destruction of pancreatic proteins, but often cause an allergic reaction.arrow_forwardplease answer a and barrow_forward

My mom's a physician with her own office here in town. I know that my mom is participating in a clinical trial for a new lactose intolerance test that measures blood glucose. Now I wonder if I'm lactose intolerant. I once had really bad stomach aches when I ate ice cream. Maybe that's why? If we go to her office, we could try to participate in the trial and if we ask nicely, she might give us the data. Wouldn't it be nice to know for sure if you are lactose intolerant? Xiao-Ma: Yes, I would love that! Sanjeet: And you know what's interesting when I was a baby, I didn't have these issues but I was able to digest milk just fine as I was breastfed. Chris: Wow that's fascinating-so as a baby you probably did produce the lactase enzyme and, if you are right, then your body at some point just stopped making it. Suddenly biology is starting to be more interesting... Esiankiki: Well, that would explain why…arrow_forward
