Cheat Sheet
- Light-Dependent vs Light-Independent Reactions -
Make sure you can distinguish the light reactions (producing ATP and NADPH in the thylakoid membranes) from the Calvin cycle (fixing CO2 into glucose in the stroma). A helpful mnemonic is "Light Delivers bright Energy, Calvin Crafts Carbs." Using practice photosynthesis and cellular respiration comparison charts from reputable sources like Khan Academy will solidify how energy carriers shuttle between these stages.
- Stages of Cellular Respiration -
Recall that cellular respiration occurs in three main stages: glycolysis in the cytosol, the Krebs cycle in the mitochondrial matrix, and the electron transport chain along the inner membrane. A handy mnemonic is "Good Kids Eat" (Glycolysis, Krebs, Electron transport) to recall the sequence quickly. Reviewing cell respiration questions on platforms like HHMI BioInteractive will strengthen your command of reaction inputs and outputs.
- Balancing the Equations -
Master the balanced equations: photosynthesis 6CO2 + 6H2O → C6H12O6 + 6O2 and cellular respiration as its reverse equation. Practice writing these in your free photosynthesis and cellular respiration test to build recall under time pressure. Checking your work against textbook standards (e.g., Campbell Biology) ensures you capture every molecule and coefficient correctly.
- ATP Yield Breakdown -
Understand that glycolysis yields 2 ATP, the Krebs cycle nets 2 ATP, and the electron transport chain can produce up to ~34 ATP per glucose, totaling about 38 ATP under ideal conditions. Knowing where most ATP is generated helps you tackle cell respiration questions on ATP accounting. A quick tip is to memorize "2-2-34" as your go-to summary for ATP yield breakdown.
- Electron Carriers & Pathway Integration -
Learn how NADP+/NADPH shuttle electrons in photosynthesis and how NAD+/FAD do the same in respiration to drive ATP production. Drawing electron flow diagrams for both processes in your photosynthesis practice will illuminate the elegant interplay between these pathways. University of Illinois resources emphasize that mastering these carriers unlocks deeper insights into the energy transformation in cells.
