1. The problem statement, all variables and given/known data I am writing my lab report. It required me cite three articles. My experiment name is effect of temperature on enzyme(catechol oxidase) activity. I just wanted to write on my own because i know some of it. And three articles are too much. And I tried my university's library webpage, Google scholar to find the article related to my subjct, but could not find anything related to it. If I found one, always a single thing does not fits such as the article I found was about temp+pressure, not just temp. Is there any helpful website to find scientific articles? Or if you know an article related to this subject, can you recommand it to me?
