chapter 9 and 10 - Coggle Diagram

- - - - NADH/FADH2 donate e- to cytochromes
      - O2 = final acceptor -> H2O
    - - H+ pumped -> intermembrane space
      - Proton-motive force spins ATP synthase (~26-28 ATP)
  - - - PFK, citrate, ATP
- - - - H2O split -> O2, e- ->NADPH; ATP via photophosphorylation
    - - PS I only; boosts ATP; no NADPH/O2
    - - H+ inside thylakoid -> stroma through ATP synthase
  - - - Respiration: NADH, FADH2
      - Photosynthesis: NADPH
    - - Respiration: food → O2
      - Photosynthesis: H2O → NADP+/CO2
    - - Both use ETC + H+ gradient + ATP synthase
      - Location differs: cristae vs thylakoids
    - - Glycolysis predates O2 atmosphere
      - Photosystems likely evolved from cyanobacteria
    - - Fermentation (no ETC)
      - C4/CAM reduce photorespiration
