3. Unit 1: Chemistry of Life

The chemistry of life introduces the basic chemical principles that underlie all biological processes. This unit covers the properties of water, the structure of carbon-based molecules, and the function of biological macromolecules.

3.1. Water and Its Properties

Water’s unique properties are crucial for life. Its polarity allows it to form hydrogen bonds, which give it high cohesion, adhesion, and surface tension. Water also has a high specific heat capacity, which helps moderate temperature. Its ability to act as a versatile solvent enables biochemical reactions to occur within cells and organisms.

Polarity: Water is a polar molecule due to the unequal sharing of electrons between oxygen and hydrogen atoms.
Hydrogen Bonds: These bonds form between water molecules, contributing to water’s unique properties.
Cohesion and Adhesion: Cohesion is the attraction between water molecules, while adhesion is the attraction between water molecules and other surfaces.
High Specific Heat Capacity: Water can absorb a large amount of heat without a significant temperature change, helping to stabilize temperatures in organisms and environments.
Versatile Solvent: Water’s polarity allows it to dissolve many substances, making it an excellent solvent for biological reactions.

3.2. Carbon and Molecular Diversity

Carbon’s ability to form four covalent bonds allows it to create a wide variety of complex molecules. Organic molecules, which contain carbon, are the foundation of life. Functional groups attached to carbon skeletons determine the properties and reactivity of these molecules.

Carbon Bonding: Carbon can form single, double, and triple bonds, creating diverse molecular structures.
Isomers: Molecules with the same molecular formula but different structures and properties.
Functional Groups: Chemical groups attached to carbon skeletons that influence the properties and reactivity of organic molecules, such as hydroxyl (-OH), carboxyl (-COOH), and amino (-NH2) groups.

4. Unit 2: Cell Structure and Function

This unit explores the structure and function of cells, the basic units of life. Topics include cell organelles, membrane structure and function, cellular respiration, photosynthesis, and cell communication.

4.1. Cell Structure

Cells are divided into two main types: prokaryotic and eukaryotic. Prokaryotic cells lack a nucleus and other membrane-bound organelles, while eukaryotic cells have a nucleus and complex organelles that carry out specific functions.

Prokaryotic Cells: Simple cells found in bacteria and archaea. They lack a nucleus and other membrane-bound organelles. Their DNA is located in the nucleoid region.
Eukaryotic Cells: More complex cells found in plants, animals, fungi, and protists. They contain a nucleus and other membrane-bound organelles, such as mitochondria, endoplasmic reticulum, and Golgi apparatus.
Organelles: Structures within eukaryotic cells that perform specific functions. Examples include mitochondria (energy production), ribosomes (protein synthesis), and lysosomes (waste disposal).

4.2. Membrane Structure and Function

The cell membrane is a selective barrier that regulates the passage of substances into and out of the cell. It is composed of a phospholipid bilayer with embedded proteins.

Phospholipid Bilayer: The basic structure of the cell membrane, consisting of two layers of phospholipids with hydrophobic tails facing inward and hydrophilic heads facing outward.
Membrane Proteins: Proteins embedded in the cell membrane that perform various functions, such as transport, enzymatic activity, and cell signaling.
Transport: The movement of substances across the cell membrane. This can occur through passive transport (diffusion, osmosis, facilitated diffusion) or active transport (requires energy).

4.3. Cellular Respiration

Cellular respiration is the process by which cells convert glucose into ATP, the primary energy currency of the cell. This process occurs in three main stages: glycolysis, the Krebs cycle, and the electron transport chain.

Glycolysis: The breakdown of glucose into pyruvate, occurring in the cytoplasm. It produces a small amount of ATP and NADH.
Krebs Cycle (Citric Acid Cycle): Occurs in the mitochondrial matrix. Pyruvate is converted into acetyl-CoA, which enters the Krebs cycle, producing ATP, NADH, and FADH2.
Electron Transport Chain (ETC): Located in the inner mitochondrial membrane. NADH and FADH2 donate electrons to the ETC, generating a proton gradient that drives ATP synthesis through chemiosmosis.

4.4. Photosynthesis

Photosynthesis is the process by which plants and other autotrophs convert light energy into chemical energy in the form of glucose. This process occurs in two main stages: the light-dependent reactions and the Calvin cycle.

Light-Dependent Reactions: Occur in the thylakoid membranes of chloroplasts. Light energy is absorbed by chlorophyll and used to split water molecules, producing ATP, NADPH, and oxygen.
Calvin Cycle (Light-Independent Reactions): Occurs in the stroma of chloroplasts. ATP and NADPH from the light-dependent reactions are used to convert carbon dioxide into glucose.

4.5. Cell Communication

Cell communication is the process by which cells transmit and receive signals, allowing them to coordinate their activities. This involves three main stages: reception, transduction, and response.

Reception: A signaling molecule (ligand) binds to a receptor protein on the cell surface or inside the cell.
Transduction: The signal is converted into a form that can bring about a cellular response. This often involves a series of relay molecules in a signal transduction pathway.
Response: The cell responds to the signal, leading to a change in gene expression or cellular activity.

5. Unit 3: Genetics

Genetics explores the principles of heredity and gene expression. Topics include meiosis, Mendelian genetics, chromosome structure, DNA replication, protein synthesis, and gene regulation.

Meiosis is a type of cell division that produces haploid gametes (sperm and egg cells) from diploid cells. This process involves two rounds of division, resulting in four genetically distinct daughter cells.

Meiosis I: Homologous chromosomes separate, reducing the chromosome number from diploid to haploid.
Meiosis II: Sister chromatids separate, similar to mitosis, resulting in four haploid daughter cells.
Genetic Variation: Meiosis increases genetic variation through crossing over (exchange of genetic material between homologous chromosomes) and independent assortment (random arrangement of chromosomes during metaphase I).

5.2. Mendelian Genetics

Mendelian genetics explains the basic principles of inheritance, based on Gregor Mendel’s experiments with pea plants. Key concepts include genes, alleles, genotype, and phenotype.

Genes and Alleles: Genes are units of heredity that determine traits. Alleles are different versions of a gene.
Genotype and Phenotype: Genotype is the genetic makeup of an organism, while phenotype is the observable traits.
Dominance and Recessiveness: Dominant alleles mask the expression of recessive alleles in heterozygous individuals.
Punnett Squares: Diagrams used to predict the possible genotypes and phenotypes of offspring based on the genotypes of the parents.

Enzymes Involved: Key enzymes include DNA polymerase (synthesizes new DNA strands), helicase (unwinds the DNA double helix), and ligase (joins DNA fragments).
Semiconservative Replication: Each new DNA molecule consists of one original strand and one newly synthesized strand.
Accuracy: DNA replication is highly accurate, thanks to the proofreading activity of DNA polymerase.

5.5. Protein Synthesis

Protein synthesis is the process by which cells build proteins based on the genetic information encoded in DNA. This process involves two main stages: transcription and translation.

Transcription: DNA is transcribed into mRNA (messenger RNA) by RNA polymerase.
Translation: mRNA is translated into a protein by ribosomes. tRNA (transfer RNA) molecules bring amino acids to the ribosome, where they are assembled into a polypeptide chain.
Genetic Code: The set of rules by which information encoded in genetic material (DNA or RNA) is translated into proteins.

5.6. Gene Regulation

Gene regulation is the process by which cells control the expression of genes. This allows cells to respond to changing environmental conditions and carry out specific functions.

Prokaryotic Gene Regulation: Often involves operons, which are clusters of genes that are regulated together.
Eukaryotic Gene Regulation: More complex, involving transcription factors, enhancers, and silencers.
Epigenetics: Changes in gene expression that do not involve alterations to the DNA sequence. Examples include DNA methylation and histone modification.

6. Unit 4: Evolution

Founder Effect: A small group of individuals colonizes a new area, leading to a loss of genetic diversity in the new population.

6.3. Gene Flow

Gene flow is the movement of genes between populations. This can introduce new alleles into a population and increase genetic diversity.

Migration: The movement of individuals from one population to another.
Hybridization: The interbreeding of individuals from different populations.

6.4. Speciation

Speciation is the process by which new species arise. This can occur through various mechanisms, including allopatric speciation and sympatric speciation.

Allopatric Speciation: A population is divided by a geographic barrier, leading to reproductive isolation and the formation of new species.
Sympatric Speciation: New species arise within the same geographic area, often through mechanisms such as polyploidy or sexual selection.
