- RESPIRATION
- ELECTRON TRANSPORT CHAIN (ETC)
- oxidative phosphorylation
- cyanide is an oxygen inhibitor (die)
- Electron Transfer Chain
- MEASURING RESPIRATION
- usually use yeast cells
- respire anaerobically & aerobically & multiply quickly
- measure oxygen uptake
- vol. = pie r2 x distance water moved
- Measure carbon dioxide output
- pH indicator (carbonic acid is acidic)
- dehydrogenase activity
- DCPIP turns colourless
- methylene blue turns colourless
- usually use yeast cells
- LINK REACTION
- occurs on inner mitochondrial membrane to matrix
- carbon dioxide & lipid will diffuse out
- The Link Reaction
- PROTEINS
- only when starved
- protein is converted into amino acids
- amino acids form pyruvate & acetyl co.A
- ANAEROBIC CONDITIONS
- only 2 ATP molecules are made
- in animals & bacteria
- lactic acid produced
- in plants
- ethanoic acid & carbon dioxide produced (plant will die)
- KREBS CYCLE
- occurs in mitochondrial matrix
- oxidative phophorylation
- The Krebs Cycle
- LIPIDS
- energy store when sugar levels are low
- fat converted into fatty acids or glycerol
- glycerol forms TP
- fatty acids forms acetyl co.A
- twice the amount of energy is made
- GLYCOLYSIS
- occurs in cytoplasm (cell membrane to outer mitochondrial membrane)
- Glycolysis
- substrate level phophorylation
- insulin is the glucose carrier (moves by passive transport)
- ELECTRON TRANSPORT CHAIN (ETC)
