Niklelel Posted October 28, 2021 Report Share Posted October 28, 2021 Hello, I am writing this because I'm not sure if this is a good idea for my IA or not. I want either measure the effect of caffeine on pepsin activity, or effect of temperature on pepsin activity (or maybe effect of temperature on the effectiveness of antacids in inhibiting pepsin activity?)

I don't want to sound rude but this seems like more of a biology IA topic rather than chemistry, it would be great as a bio one tho. maybe u should check the AHL topics and base your research question on one of the topics? or do something related to titration since its simple. i did mine on catalysts and different temperatures effect on the activation energy and plot an Arrhenius plot so obviously it was experiment based + there's a drive link below too i have resources in the "chemistry IA" folder that could perhaps help u choose ur question, u could maybe use questions similar to the ones in the IA samples or even use the same ones? once u've got a good question the rest is easy, good luck! https://drive.google.com/drive/folders/1qPguSccebtOLuFFudVNo7Xd4WrmLH-0g?usp=sharing Reply Link to post Share on other sites More sharing options...

I just wanted to pop in and ask out of curiosty -- how would you perform the IA as a biology one? How can I get pepsin? And how would the experiment go?

And how would the experiment go? hey, usually schools provide pepsin for experiments, but if u have to buy it ur self capsules are available in most, if not all pharmacies, some require a prescription and some don't but i think asking ur school to provide pepsin capsules would be best + and for the experiment i'm not quite sure how it would go since i haven't done this one but i'm certain you'll find resources and similar experiments on the internet Reply Link to post Share on other sites More sharing options...
