Recent Tutoring Session Reviews
"The student has a Biology exam tomorrow, on cellular respiration and photosynthesis. We went over, in detail, both processes - glycolysis, pyruvate decarboxylation, citric acid cycle, electron transport chain, light and dark reactions, and the different types of phosphorylation, and photophosphorylation. We talked about the components of each process as well, including ATP synthase, electron carriers, photosystems, and pigments. We also went over the similarities and differences between the two processes. She took lots of notes and she that she felt much more confident for her exam tomorrow, and would email me her grades when she got them. She said that she now understood the processes more, and thought that her notes would be very helpful in her studying. We made tables and summaries together so that she could see the big picture for the processes."
"Went over key questions for this unit on cell structure, membrane structure, diffusion and transport."
"Today we reviewed prokaryotic transcription and the overview of eukaryotic transcription. We then covered mRNA modifications and transcription factors in eukaryotic transcription, such as the 5' cap, the 3' poly-A-tail and alternative splicing. She had some trouble understanding the structure of the mature mRNA molecule as it transitioned from a primary transcript to a mature mRNA molecule, and to remedy this I drew her a diagram of what the 5'cap and the 3' poly A-tail looked like, as well as what alternative splicing looked like in a diagram. This really helped her understand the topic. We also discussed the beginning of translation, the acceptor site, and the anticodon site of the actual tRNA molecule. She had the most difficulty understanding the TATA box in the core promoters of eukaryotes, as well as the E site, the P site, and the A site of tRNA and how translation occurred overall. To remedy this, we watched a short video that demonstrated the movement of tRNA as it moved from the P site to the E site and how another tRNA molecule came into the A site and helped the polypeptide chain grow. After seeing this movement, she understood the overall process."
