Recent Tutoring Session Reviews
"The student and I discussed thermodynamics problems concerning entropy. We talked about how to use thermodynamic tables to identify properties of pure substances and the conceptual underpinnings of solving the problems."
"Today, the student and I covered buffer solutions. We calculated the pH and pKas of buffer solutions using the Henderson-Hasselbach equation. We also determined how to prepare a specific buffer. We reviewed his homework together."
"The student and I reviewed two questions from a recent test that had been difficult for him. The questions were somewhat open-ended, and no answer key was provided. Accordingly, our discussion was focused on responses that would have been reasonable. We also went through slides that had been presented in class. The subject matter focused on bioremediation, and our conversation revolved around key terms, chemical principles, and features of biological organisms that drive design of bioremediation techniques. Additionally, we focused on biofilms and discussed how some of the biological features exploited in bioremediation are the same features that make natural incidences of biofilms potentially threatening to humanity. For instance, biofilms in hospitals are particularly resistant to destruction, which in turn causes difficulty in accomplishing sterilization of a space."
"The student and I had our last session today. We covered thermodynamics. Mainly, I explained how phase changes affect the internal energy (and both kinetic and potential) of a system. We also discussed how phase changes are indicative of constant temperature and why this is true."
"During this session, we continued to discuss the details of enzyme kinetics. We also looked at how to calculate values such as kcat using enzyme concentration and vmax. We then looked at how to use the half life of an uncatalyzed reaction to compare it to the rate of the enzyme catalyzed reaction. We also discussed the regulation mechanism of ATCase via ATP and CTP from the production of purines or pyrimidines. We ended the session by reviewing how different types of inhibitors change the apparent values of Km and vmax on a mechanism level."
"The student wanted to cover 2 specific questions really for a test she was having the next day, and we did just that. She did both questions with little guidance from me with impressive speed. I'm confident that she will do well on her test tomorrow! Good luck!"
