Cellular Respiration

Cellular Respiration

1. Fermentaion

   • Lactic Acid Fermentation: Reduction of Pyruvate into Lactic Acid
   • Alcohol Fermentation: Reduction of Pyruvate to Ethyl Alcohol

2. Stages of Cellular Respiration

   • Glycolysis: Glucose is turned into 2 pyruvate and turns 2 NAD+ into 2 NADH. It also has a net gain of 2 ATP
   • Pre Krebs: Oxidises Pyruvate and turns it into Acetyl CoA
     • Acetyl CoA: Compound used in Citric Acid Cycle
   • Krebs Cycle: Creates FADH and NADH and releases CO2. Also creates 2 ATP
   • OxidativePhosphorylation: Contains ETC and Chemiosmosis
     • Electron Transport Chain: Electron carrying proteins that oxidise and reduce NADH and FADH to create H+ in the intermembrane
     • Chemiosmosis: Due to concentration gradient of H+ ions, the ATP synthase sucks them in and uses that energy to turn ADP+P into ATP, usually creates around 34 ATP

3. Redox: Leo the Lion says GER

   • Loss of electrons is known as Oxidatoin
   • Gain of Electrons is Reduction
