Fall Semester Welcome and Academic Support Services

Introduction

• Welcome to the second week of the fall semester.
• Elizabeth Abraham - Coordinator for Academic Support Services.

Supplemental Instruction (SI)

• SI stands for Supplemental Instruction.
• Based on course material by trained SI leaders.
• Scheduled right before or after classes for convenience.

SI Leader for Anatomy and Physiology

• Ethan is the SI leader, a level three tutor.
• Available for questions and is a valuable resource.

Other Courses with SI

• Includes chemistry, physics, and around 16-17 courses.
• Resources available on the website, free of charge.
• Not mandatory, but highly encouraged.

Peer Tutoring

• For science courses at the Science Learning Center.
• For other subjects (language, business, engineering, accounting) next to the office in the General South Building.
• Open door policy for any questions or concerns.

Join the Team

• Paid opportunity for students with a B+ or better in courses.
• Leadership experience beneficial for resumes.

Ethan’s SI Sessions

• Ethan introduces himself and promotes SI sessions.
• Claims that those attending SI sessions average a higher grade.
• Sessions involve group study and interactive learning methods.
• Access to VR, diagrams, and anatomical models at SLC.
• Sessions scheduled at 4:00 PM right before class.

Chemistry Lecture Overview

Atomic and Molecular Concepts

• Quick review of atomic structures, valence electrons, and bonds.
• Focus on properties of water.

Properties of Water

• Water is H2O, but has unique properties such as cohesion, surface tension.
• Water as a universal solvent; importance in life forms.
• Observations on droplets of water and their interactions.
• Water can form a 'jelly-like' state, not just liquid.
• Cohesive properties allow phenomena like water bridges.

Chemical Reactions and Equilibrium

• Importance of understanding chemical equations in bodily functions.
• Decomposition and displacement reactions explained.
• Reactions can be forward or reverse depending on cell needs.

Enzymes and Catalysts

• Enzymes as biological catalysts, increasing reaction speed.
• Influence of concentration, temperature, and catalysts on reactions.

Acids, Bases, and Buffers

• Acids donate protons; bases accept protons.
• Importance of pH in bodily functions and stability.
• Bicarbonate system as a key blood buffer system.

Organic Molecules and Biochemistry

Carbohydrates

• Monomers and polymers like glycogen and starch.
• Energy storage and usage.

Lipids

• Types include triglycerides and phospholipids.
• Role in energy storage and cell membrane structure.

Proteins

• Made of amino acids; peptide bonds.
• Functions include structural, enzymatic, transport, and immune response.

Nucleic Acids

• DNA and RNA; nucleotides as building blocks.
• Role in genetic information and cellular functions.

Incident During Lecture

• Disruption in class causing discussion on physiological responses.

Conclusion

• Brief touch on polymers and monomers.
• Dehydration and hydrolysis reactions in building and breaking down compounds.
• Importance of understanding biochemical properties and reactions in physiology.
