Study Notes
Biology Concepts
- Earth's Formation: About 4.5 billion years ago, Earth was a hot, rocky ball.
- Hydrothermal Vents: Located at the ocean floor, these vents release chemicals.
- Carbohydrates: Provide quick energy.
- Lipids: Store energy.
- Enzymes: Catalysts that speed up chemical reactions in living beings.
- Lactase: Breaks down the sugar in milk.
- Living Organisms: Made of cells.
- Eukaryotes: Have organelles like the nucleus.
- Prokaryotes: Lack membrane-bound organelles (like bacteria).
- Scientific Names: Every species has a unique name consisting of genus and species.
Homeostasis and Cellular Processes
- Maintaining Balance: Homeostasis is the process of maintaining stable conditions (pH etc.) in organisms.
- Cell Membranes: These are phospholipid bilayers.
- Diffusion: Balancing concentration gradients.
- ATP Production: Cellular respiration generates energy — ATP.
- Photosynthesis: Plants use sunlight to make glucose.
DNA and Protein Synthesis
- DNA Composition: Nucleotides (phosphate, sugar, base).
- Transcription: DNA is copied to RNA.
- Codons: Specific RNA sequences that code for amino acids.
- Protein Synthesis: Manufacturing proteins using codons.
- mRNA: Carries genetic instructions for protein production.
- tRNA: Transports amino acids to assemble proteins.
Chromosomes and Reproduction
- Chromosome Structure: DNA is compacted into chromosomes.
- Meiosis: Genetic material exchange between chromosomes during cell division.
- Crossing Over: Exchange of genetic material.
Cellular Respiration and Photosynthesis
- Cellular Respiration: Uses oxygen and glucose to produce ATP.
- Photosynthesis: Chlorophyll absorbs light energy to split water and produce glucose.
- Nitrogenous Bases: Adenine, Thymine, Guanine, Cytosine.
Enzyme Function and Cellular Processes
- Enzyme Damage: Enzymes can denature if their environment changes dramatically.
- Mitosis and Meiosis: Mitosis creates identical cells, meiosis creates different cells.
- Myelin Sheath: Speeds up action potentials in nerve cells.
- Prokaryotes vs. Eukaryotes: Prokaryotes lack organelles; eukaryotes have them.
Beneficial Mutations
- Mutations: Changes in DNA.
- Benefits: Some mutations improve an organism's fitness (like camouflage).
