L>BSC 2010C thing 9 : Respiration notesChapter 9 : RespirationRespiration is a catabolic reaction the breaks down glucose come release power ( ATP ). Energy is save on computer in the cell together ATP or NADH. Glucose + Oxygen -----> Carbon dioxide + Water + Energy. C6H12O6 + 6 O2 ---------> 6 CO2 + 6 H2O. Aerobic respiration : offers oxygen.Anaerobic respiration : does not use oxygen.Aerobic respirationAerobic respiration is divided into three key stages:Glycolysis, Citric mountain cycle and Electron carry chain.Glycolysis: Glucose ( 6 carbon atoms) is separation into 2 molecules of glyceraldehyde phosphate (3 carbon each), then these are turned into pyruvate (3 carbons each). This to produce 2 ATP and also 2 NADH. Glycolysis takes ar in the cytoplasm.Citric mountain cycle (or Krebs cycle) The key chemicals space Acetyl CoA (2 carbons), citrate (6C), and also oxaloacetate (4C). Diagram. This produces 2 ATP, 6 NADH and also 2 FADH2. The citric mountain cycle takes location inside the mitochondria, and also it produces the CO2 that you breath out.Electron carry chainThis stage produces many of the energy ( 32 ATP molecules, compared to just 2 ATP because that glycolysis and also 2 ATP because that citric mountain cycle). This stage converts the NADH and FADH2 right into ATP. The electron transport chain takes ar in the mitochondria.The electron carry chain works as a proton pump: that pumps hydrogen ion (protons) through the membrane, and only enables them back through a protein (ATP synthase) which makes ATP. The electron transfer chain supplies oxygen to accept electrons at the finish of the chain (the electrons integrate with hydrogen ions and also oxygen to develop water molecules).Summary: the 3 stages the Aerobic RespirationGlycolysis Citric acid cycleElectron transfer chainCytoplasmMitochondriaMitochondriaBreaks under Glucose come PyruvateTurns Pyruvate right into CO2Converts NADH and FADH2 right into ATP2 ATP2 NADH2 ATP6 NADH2 FADH2 32 ATPCatabolism that food Cells have the right to use numerous organic molecules in respiration: not just glucose.Carbohydrates are broken down making use of all 3 stages that respiration (glycolysis, citric mountain cycle and the electron transfer chain).Lipids are broken down come glyceraldehyde, for this reason they walk through part of glycolysis, climate the citric mountain cycle and also the electron move chain.Proteins room deaminated (the amino group is removed), and then convert in Acetyl CoA, i beg your pardon is supplied in the citric mountain cycle, and also then the electron transfer chain (so they skip glycolysis).Anaerobic respirationAnaerobic respiration go not use oxygen.Only glycolysis can occur, for this reason it just produces 2 ATP molecules. Solitary celled organisms eg bacteria and also yeast can survive anaerobically.Large pets (eg humans) build up one oxygen debt as soon as anaerobic.During anaerobic respiration, pyruvate builds up and also is convert to :lactate ( lactic mountain ) in animals.
