Robert - Know your tutor
My name is Robert Motter, and I am a Chemistry, Biology, and Mathematics tutor. I have satisfactorily helped students in all levels of education. I primarily help High School and College students. I emphasize the importance of understanding the material and being able to apply it to more complicated problems. Being intentional with the formulas and theories you use lead to better outcomes, and I focus on that with my students. I am willing to help you understand whatever you feel you need help with, and I always prioritize understanding and learning over getting the correct answer as soon as possible. I promote a chill learning environment in which students feel comfortable to ask questions no matter how "stupid" they may think those questions are. I definitely understand being intimidated by strict authority figures such as tutors or teachers, and I promise that will not be a concern with me. I teach different levels of math ranging from Pre-Algebra all the way to AP Calculus BC for High School. Those equivalents for college are Calculus II and below (including any sort of remedial math). I also offer Introduction to Statistics. The type of students I tend to attract are those who follow a Pre-Med track, because I am able to assist with a lot of the required classes. However, I am willing to help students of any background and welcome all. I am looking forward to working with you!

Mathematics concepts taught by Robert
The Student and Tutor reviewed a wide range of multiple-choice questions covering topics 13, 14, and 15 (parts 1 and 2) related to microbial communities, the innate immune system, and the adaptive immune system, in preparation for an upcoming exam. They focused on identifying correct answers and understanding underlying academic concepts. The Student's exam is scheduled for Tuesday, and they discussed future scheduling around Thanksgiving break, with the next session planned for Sunday.
Microbial Ecosystems & Their Dynamics
Innate Immunity: First Lines of Defense
The Complement System: A Cascade of Protection
Adaptive Immunity: Specificity
Diversity & Memory
Immune System Regulation & Tolerance
The Student and Tutor worked through the detailed catalytic mechanism of an enzyme, specifically identifying the active site residues (Serine, Histidine, Aspartate) and tracing the step-by-step process of peptide bond cleavage. They focused on proton transfers, nucleophilic attacks, and the formation and breakdown of tetrahedral intermediates, ultimately demonstrating the enzyme's regeneration. The session confirmed the mechanism aligns with Chymotrypsin, a classic enzyme studied in biochemistry.
Role of Proton Transfer & Enzyme Regeneration
Chymotrypsin Mechanism: Peptide Bond Cleavage
The Catalytic Triad
Enzyme Active Site & Substrate Binding
Student and Tutor reviewed topics 16 and 17, focusing on host immune system failure, immunodeficiencies, immune surveillance, autoimmunity, and the principles of vaccination. They discussed different types of immunity acquisition, various vaccine platforms, and the importance of adjuvants and boosters. The next session will involve exam preparation and practice.
Adjuvants
Boosters
and Herd Immunity
Host Defense Impairment
Diverse Vaccine Types and Their Mechanisms
Vaccination: Active vs. Passive Immunity
Primary vs. Secondary Immunodeficiency
Immune Surveillance & Loss of Self-Tolerance
The Student and Tutor completed a detailed review of the adaptive immune system, discussing the distinct roles and activation mechanisms of B and T cells, the structure and functions of various antibody classes, and the significance of MHC molecules. They analyzed how immunological memory is formed and sustained, and explored the intricate processes of immune regulation and potential dysfunctions. The next session is scheduled for November 1st.
Adaptive Immunity Fundamentals & Innate Connection
Antigen-Epitope Recognition & Lymphocyte Specificity
Lymphoid Organs: T & B Cell Development and Activation Hubs
T Cell Activation: The Three-Signal Model
B Cell Responses: T-Independent vs. T-Dependent Antibody Production
Antibody Structure
Classes
and Effector Functions
Student and Tutor worked through several complex biochemistry problems from a worksheet, focusing on topics such as dipeptide structure and pKa determination, plotting protonation curves, optimizing protein-ligand interactions, and analyzing the thermodynamic effects of amino acid mutations on protein stability. They also discussed an ambiguous homework question that the Student plans to clarify with their instructor.
Dipeptide Structure & pH Titration
Non-Covalent Interactions in Protein Binding
Impact of Amino Acid Mutations on Protein Binding
Thermodynamics of Protein Folding: ∆H and ∆S
Quaternary Structure Stability in Aqueous Solution
Optimizing Protein-Molecule Interactions by pH
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.
Amino Acid Properties and Secondary Structures
pH Regulation of Protein Conformation
Hemoglobin's Oxygen Binding Mechanism
Blood Buffer System and Le Chatelier's Principle
Amino Acid Ionization and Isoelectric Point (pI)
Dipeptide Charge State Feasibility
