3 similarities and 3 differences between photosynthesis and respiration

C – Describe overall process of respiration Objectives E – Define keywords C – Describe overall process of respiration A – Explain in full respiration and the stages of both anaerobic and aerobic respiration

Glycolysis - Oxidation Glucose ADP NAD ATP NADH Pyruvate

Krebs cycle 3 molecules NADH and FADH2 produced Electron transfer chain High energy electrons brought in from glycolysis H+ + 1/2O2 + 2e- 38 molecules ATP

Fermentation Anaerobic respiration Occurs when oxygen is limited

NAD is oxidised Hydrogen combines with pyruvate Forming :- lactate in animals ethanol in plants / fungi

Glycolysis can continue… Producing some ATP Forming 2 ATP per glucose molecule Compared with 38 ATP per glucose molecule with aerobic respiration
