Major Course Topics

Atoms & Molecules

This topic introduces the chemical basis of life, focusing on the structure and properties of atoms and molecules essential for biological systems.

• Atomic Structure: Identify components of an atom (protons, neutrons, electrons) and their arrangement.

• Chemical Bonds: Compare covalent and ionic bonds; understand polar vs. nonpolar covalent bonds.

• Water Properties: Explain the emergent properties of water, including cohesion, adhesion, and polarity.

• Organic Molecules: Recognize the structure and function of carbohydrates, lipids, proteins, and nucleic acids.

• Polymerization: Understand how monomers form polymers through dehydration synthesis.

Cells & Cellular Functions

This section explores the structure and function of prokaryotic and eukaryotic cells, as well as the organization and specialization of cellular components.

• Cell Types: Compare prokaryotic and eukaryotic cells.

• Cellular Organelles: Identify and describe the function of major organelles (nucleus, mitochondria, endoplasmic reticulum, etc.).

• Membrane Structure: Relate the structure of biological membranes to their function in transport and communication.

• Endosymbiotic Theory: Explain the origin of mitochondria and chloroplasts.

Respiration & Photosynthesis

This topic covers the processes by which cells obtain and use energy, focusing on cellular respiration and photosynthesis.

• Cellular Respiration: Identify the steps and outputs of glycolysis, the citric acid (Krebs) cycle, and oxidative phosphorylation.

• Photosynthesis: Describe the light reactions and Calvin cycle, and their roles in energy capture and conversion.

• Energy Flow: Connect the processes of respiration and photosynthesis to the cycling of matter and energy in ecosystems.

Mitosis & The Cell Cycle

This section explains how cells divide and the importance of cell cycle regulation in growth and development.

• Cell Cycle Phases: Describe the stages of the cell cycle (G1, S, G2, M) and their regulation.

• Mitosis: Explain the process and significance of mitosis in asexual reproduction and growth.

• Chromosome Structure: Recognize chromosomes as distinct units of genetic material.

• Cell Cycle Regulation: Understand the importance of checkpoints and regulatory proteins.

Sex: Meiosis & Fertilization

This topic covers the mechanisms of sexual reproduction, including meiosis and fertilization, and their roles in genetic diversity.

• Meiosis: Compare and contrast meiosis and mitosis; explain the reduction of chromosome number and genetic variation.

• Fertilization: Describe the fusion of gametes and restoration of diploid chromosome number.

• Genetic Variation: Explain the sources of genetic variation, including crossing over and independent assortment.

Genetics

This section introduces the principles of inheritance, gene structure, and the molecular basis of genetic variation.

• Mendelian Genetics: Describe Mendel's laws of inheritance and predict outcomes using Punnett squares.

• Gene Structure: Define what a gene is and how it encodes information for traits.

• Alleles & Phenotypes: Relate genotype to phenotype and explain dominance, codominance, and incomplete dominance.

• Genetic Recombination: Understand the effects of recombination and independent assortment on genetic diversity.

Key Definitions & Concepts

• Atom: The smallest unit of matter that retains the properties of an element.

• Molecule: Two or more atoms held together by covalent bonds.

• Cell: The basic structural and functional unit of all living organisms.

• Organelle: Specialized subunit within a cell with a specific function (e.g., mitochondria, nucleus).

• Gene: A segment of DNA that encodes information for a specific trait.

• Allele: Different forms of a gene found at the same locus on homologous chromosomes.

• Genotype: The genetic makeup of an organism.

• Phenotype: The observable characteristics of an organism resulting from its genotype.

• Meiosis: A type of cell division that reduces the chromosome number by half, producing gametes.

• Mitosis: A type of cell division resulting in two identical daughter cells.

Important Equations

• Photosynthesis:

$6CO_2 + 6H_2O + \text{light energy} \rightarrow C_6H_{12}O_6 + 6O_2$

• Cellular Respiration:

$C_6H_{12}O_6 + 6O_2 \rightarrow 6CO_2 + 6H_2O + \text{energy (ATP)}$

• Mendel's Law of Segregation:

$\text{Each individual has two alleles for each gene, which segregate during gamete formation.}$

• Hardy-Weinberg Equation:

$p^2 + 2pq + q^2 = 1$

where $p$ and $q$ are the frequencies of two alleles in a population.

Course Policies & Inclusive Environment

• Respect and Inclusion: The course values diversity and aims to create an inclusive environment for all students.

• Academic Integrity: Students are expected to adhere to university policies regarding honesty and ethical conduct.

• Accessibility: Accommodations are available for students with documented needs.
