Biology tutor near me in Long Beach, CA

The Student and Tutor reviewed evolutionary biology concepts, including Darwin's theory, natural selection, genetic variation, speciation, and the fossil record. They practiced calculating allele frequency and constructing phylogenetic trees. The next session will involve further practice questions.

The Student and Tutor reviewed key concepts in Unit 4 of AP Biology, focusing on cell communication mechanisms (autocrine, paracrine, endocrine, synaptic) and the stages of cell signaling (reception, transduction, response). They then delved into the cell cycle, including interphase, M phase, checkpoints, and mitosis. The next session will cover Units 5 and 6.

The Tutor and Student reviewed the innate immune system, covering physical and chemical barriers, and the formed elements of the blood that constitute the second line of defense. They discussed cytokines as immune cell messengers and detailed the process of phagocytosis, including its various stages. The next session is planned to continue the discussion on inflammation.

The Student and Tutor reviewed the Citric Acid Cycle, covering its location, two main stages (oxidation of acetyl-CoA and regeneration of oxaloacetate), and key intermediates and enzymes. They discussed specific steps including citrate formation, isomerization, oxidative decarboxylation, and the production of energy carriers like NADH, FADH2, and GTP. The next session will be dedicated to the Electron Transport Chain (ETC), and the Student was assigned to revise the Citric Acid Cycle for a potential test.

The Tutor and Student reviewed cellular energetics, covering photosynthesis and cellular respiration, and detailed the structure and function of mitochondria. They discussed the endosymbiotic theory and the differences between aerobic and anaerobic respiration, with a plan to cover the stages of respiration and ATP yield in subsequent sessions to prepare for the AP Biology exam.

The session covered the initial stages of cellular respiration, including glycolysis, pyruvate oxidation, and the citric acid cycle. The Tutor used whiteboard explanations to detail the mechanisms, enzyme involvement, and products of each stage. The Student expressed a desire to watch animation videos for better visualization, and the next session was scheduled to review these concepts and proceed to the electron transport chain.
