Expert biology tutor using visual aids and real-world examples for engaging, foundational learning.

Ismail tutored a student from Southern Methodist University in Dallas, delving into organic chemistry concepts such as NMR and IR spectroscopy and retrosynthesis. The lesson aimed to prepare the learner for an upcoming exam, and they collaboratively worked through practice problems on structure elucidation using spectroscopic data and designing synthetic routes from given starting materials. When the student expressed feeling overwhelmed, Ismail offered encouragement and strategies for approaching exam questions.

Ismail guided Mahid through a detailed biology lesson, specifically focusing on the intricacies of glycolysis. Their discussion encompassed the enzymes involved, its regulatory mechanisms, and its importance across diverse organisms. They also explored concepts like isomers and Gibbs free energy, drawing connections between glycolysis and the Krebs cycle. Additionally, the lesson addressed the vital role of anaerobic fermentation in organisms without mitochondria. The plan for their next meeting is to delve into the Krebs cycle.

Ismail provided a cell biology lesson to Minha, delving into cell types, organelles, and the cell cycle, with a particular emphasis on mitosis and its various phases. Their discussion also covered how DNA codes for proteins and enzymes, essential for cellular functions. While no homework was formally assigned, Ismail offered additional practice if Minha desired it.

During their physics lesson, Ismail and Clarence delved into challenging concepts such as Archimedes' principle, buoyancy, the nuances between Newtonian physics and relativity, and the Bernoulli equation. Clarence received valuable advice on problem-solving strategies and insights into upcoming topics, with Khan Academy recommended as a helpful resource. They scheduled a follow-up lesson for next Wednesday, and Clarence outlined his plan to practice extensively on problems related to gravity, fluids, and relativity in preparation for his test.

Ismail helps Janette understand the citric acid cycle and the pyruvate dehydrogenase (PDH) complex. They discuss the PDH complex's three enzymes (E1, E2, E3) and five coenzymes (TPP, lipoate, CoA, FAD+, NAD+) that convert pyruvate to acetyl-CoA. Lipoate acts as a mobile arm to transfer substrates between enzymes. The citric acid cycle, starting with acetyl-CoA and oxaloacetate, produces NADH, FADH2, and GTP, regenerating oxaloacetate. They also cover the roles of coenzymes and calculating delta G and equilibrium constants, emphasizing the importance of reaction direction.

Ismail tutored Noah on organic chemistry, specifically reviewing organolithium and Grignard reagents, carbonyl reaction mechanisms, and factors influencing acidity. Noah worked through practice problems and clarified his understanding of reaction steps and stereochemical outcomes. They discussed strategies for the upcoming MCAT, focusing on conceptual understanding over rote memorization.
