A STEM Tutor Who Assists with High School and College Mathematics Courses Including Chemistry and Biology too! Stress Free with Peak Results!

The Student and Tutor reviewed several biochemistry homework problems and exam questions, focusing on protein structure, amino acid properties, the effects of pH on protein conformation, the bicarbonate buffer system, and pKa calculations. They practiced applying concepts like Le Chatelier's Principle and the Henderson-Hasselbalch equation. They also scheduled a follow-up review session.

The Student and Tutor reviewed two comprehensive microbiology topics. First, they covered the human microbiome, discussing microbial ecology, resident communities, and the impact of antibiotics and therapies. Second, they delved into the innate immune system, exploring its barriers, cellular components, recognition mechanisms, and the processes of phagocytosis and inflammation. The Student's upcoming exams and study strategies were also briefly discussed.

Student and Tutor reviewed advanced biochemistry topics including hemoglobin and myoglobin oxygen binding mechanisms, the allosteric effect, and protein solubility based on amino acid side chains and pKa values. They practiced problem-solving related to chemical cleaning agents and discussed the structural roles of specific amino acids in protein turns and the conditions inside cells affecting disulfide bond formation. They concluded by clarifying concepts of secondary and tertiary protein folding.

Student and Tutor prepared for an upcoming exam by practicing case study problems across topics including eukaryotic microorganisms, viruses, physical and chemical control of microbes, and antimicrobial drugs. They focused on applying academic concepts to scenarios and clarifying distinctions between mechanisms and definitions. The Student was advised to prioritize memorizing details regarding antimicrobial drugs and chemical control for their Thursday exam.

Student and Tutor reviewed the student's recent biochemistry exam performance and then discussed protein structure, including insights from a recent research article on protein hardening for drug development. They subsequently focused on a detailed pH problem involving the dipeptide Asp-Glu, calculating its charge at different pH values and determining its isoelectric point.

The Student and Tutor conducted an extensive review of antimicrobial drugs in Microbiology, detailing their mechanisms of action, resistance, and diagnostic tests like Kirby-Bauer and MIC/MBC. They systematically explored drug classes targeting bacterial cell walls, protein synthesis, DNA/RNA, metabolic pathways, and cell membranes, concluding with an example of combination therapy for tuberculosis.
