Cheat Sheet
- Passive Diffusion & Osmosis -
Understand that molecules move from high to low concentration down their gradient without energy input, as described by Fick's law (J = -D ΔC/Δx). For osmosis, remember water moves toward higher solute concentrations; use the mnemonic "Water Falls to Salt" to recall directionality. You'll often encounter these principles in cell transport quiz questions on membrane permeability.
- Facilitated Diffusion via Transport Proteins -
Recognize how carrier and channel proteins enable selective passage of ions and polar molecules, like glucose via GLUT-1, without requiring ATP. Recall specificity by thinking "Lock and Key," where each transporter fits only its substrate. Practice identifying examples in a biology cell transport quiz to solidify this concept.
- Primary vs. Secondary Active Transport -
Differentiate primary active transport, which uses ATP directly (e.g., Na❺/K❺-ATPase pump: 3 Na❺ out, 2 K❺ in), from secondary active transport that exploits ion gradients for co-transport (e.g., Na❺/glucose symport). A handy phrase is "ATP First, Gradient Next" to remember their order. These mechanisms are core topics in a cellular transport quiz and often tested with real-life examples.
- Bulk Transport: Endocytosis and Exocytosis -
Bulk transport moves large particles or volumes: endocytosis engulfs materials (phagocytosis & pinocytosis) while exocytosis secretes vesicle contents. Think "Cell Eating, Cell Secreting" to quickly recall both processes. These are frequent scenarios in a cell transportation quiz involving immune cell functions or hormone release.
- Electrochemical Gradients & Nernst Equation -
Use the Nernst equation (E = (RT/zF) ln([out]/[in])) to calculate an ion's membrane potential, combining concentration and electrical driving forces. At 37 °C for monovalent ions, simplify to E ≈ 61.5 mV · log([ion]out/[ion]in). Questions in a biology cell transport quiz often include this formula to predict nerve impulse and cardiac cell behavior.
