Cheat Sheet
- Cell Structure & Function -
Key organelles like the nucleus, mitochondria and endoplasmic reticulum coordinate DNA storage, energy production, and protein synthesis. The fluid mosaic model - imagine a sea of lipids with floating protein "icebergs" - explains membrane dynamics. Remember higher to lower concentration for passive transport and active transport moves against gradients using ATP.
- DNA Structure & Replication -
DNA's double helix relies on complementary base pairing (A-T and G-C) to encode genetic information. Replication is semiconservative: each new DNA molecule retains one original strand, guided by enzymes like DNA polymerase. Mnemonic "Apple Trees Grow Constantly" helps recall A-T and G-C pairings when tackling biology questions.
- Photosynthesis & Cellular Respiration -
Photosynthesis converts light energy into glucose: 6 CO2 + 6 H2O → C6H12O6 + 6 O2, while cellular respiration reverses this to release ATP. Understanding both pathways clarifies energy flow in cells and ecosystems. A quick trick: "Photo makes sugar; 'cyto' eats sugar" to keep the reactions straight.
- Mendelian Genetics & Punnett Squares -
Gregor Mendel's pea experiments revealed dominant vs recessive inheritance and the 3:1 ratio in monohybrid crosses. Use Punnett squares to predict genotypic and phenotypic ratios - key for multiple choice biology tests. Think "3 tall, 1 short" and apply dihybrid 9:3:3:1 ratios when exploring linked vs independent assortment.
- Ecosystem Levels & Energy Flow -
Ecology questions often ask for trophic levels: producers, primary consumers, secondary consumers, and decomposers, with only ~10% energy transfer each step. Remember the acronym "OPPER" for Organism, Population, Community, Ecosystem, and Biome, then Biosphere. Visualizing food webs boosts your confidence on any biology test covering ecosystems.
