Experienced Biology Tutor from De Montfort University Ready to Empower Your Learning Journey

The Student and Tutor reviewed an MCQ quiz on enzyme activity, then delved into a detailed lesson on enzyme function, specificity, and the factors influencing enzyme activity such as temperature, pH, and substrate/enzyme concentration. The session also introduced enzyme inhibition and the basic laws of thermodynamics, alongside exergonic and endergonic reactions. For follow-up, the Student was assigned practice MCQs for units 3.2, 3.3, and 3.4, and advised to review 3.4 slides for an upcoming quiz and unit exam.

The Tutor and Student began a detailed review of Unit 3: Cellular Energetics, covering enzymes, photosynthesis, and cellular respiration. They discussed key definitions, processes, and the interconnectedness of energy transfer in living organisms. For homework, the Student was asked to review questions related to the topics covered, with plans for a quick quiz and extensive practice questions in the next session to prepare for an upcoming unit quiz.

Student and Tutor began the AP Biology curriculum, starting with Unit 1: Chemistry of Life. They reviewed foundational concepts like atoms, molecules, the principle of structure and function, and the unique properties of water, including polarity, hydrogen bonding, and specific heat capacity. The session also introduced the four major macromolecules, and the Student was advised to share course materials for upcoming quiz preparation.

The student and tutor worked on calculating ion concentrations in chemistry. They practiced problems involving dissociation equations, molar mass calculations, and unit conversions to determine the concentration of specific ions in various solutions. The tutor provided additional practice examples for the student to work on.

The student and tutor reviewed stoichiometry, focusing on identifying limiting reactants and calculating excess amounts. They practiced solving problems by converting masses to moles, using mole ratios from balanced equations, and determining which reactant was in excess. The tutor provided advice on exam preparation and practice.

The Student and Tutor reviewed core stoichiometry concepts, including mole definitions, molar mass calculations, and observing decomposition reactions. They practiced solving problems involving hydrates, determining the number of water molecules of crystallization, and performed calculations using the concentration-volume-mole formula. The session also covered balancing chemical equations, applying gas volume stoichiometry to deduce hydrocarbon formulas, and identifying limiting reagents. The Tutor provided a practice PDF for the Student's upcoming exam and offered further support.
