Chapters 9 & 10: Cellular Respiration and Photosynthesis
Cellular Respiration
Breaks down glucose → ATP
Occurs in mitochondria
Exergonic (releases energy)
Reactants
Glucose (C₆H₁₂O₆)
O₂
Products
CO₂
ATP
H₂O
Stages
Pyruvate oxidation
Moves pyruvate → acetyl‑CoA
Citric Acid Cycle (Krebs Cycle)
Produces CO₂, ATP, NADH, FADH₂
Glycolysis
Glucose → 2 pyruvate + small ATP + NADH
Electron Transport Chain
Uses NADH/FADH₂ → large ATP yield
O₂ = final electron acceptor → forms H₂O
Photosynthesis
Converts light energy → glucose
Endergonic (requires energy)
Occurs in chloroplasts
Reactants
CO₂
Light
H₂O
Products
Glucose
O₂
Stages
Light Dependent Reactions
Occurs in thylakoid membrane
Uses H₂O and light
Produces O₂, ATP, NADPH
Calvin Cycle
Uses ATP and NADPH
Fix CO₂ → G3P
Occurs in stroma
Products
Glucose → used in glycolysis
CO₂ → used in Calvin Cycle
O₂ → used in ETC for oxidative phosphorylation
H₂O → used in light reactions
