The formula for cellular respiration is… C6H12O6 + O2 H2O + CO2 + 36 ATP Glycolysis! (the boring part) : Glycolysis! (the boring part) Glycolysis is an anaerobic process. Meaning it does not use oxygen. The process of glycolysis takes place in the cytoplasm. Glycolysis takes glucose, energizes it with two phosphates from ATP molecules, and splits it. This creates TWO pyruvate molecules, and TWO ADP molecules. Glycolysis! : Glycolysis! The In-Between Bit : The In-Between Bit This process really doesn’t have a name, but it is in between glycolysis and the Krebs cycle. One of the two pyruvate molecules produced in glycolysis is split, releasing carbon dioxide. A pair of electrons are transferred from the two carbon compound to a NAD+ molecule, forming NADH. This now attaches to a molecule called coenzyme A, forming acetyl CoA. Pre-step to Krebs Cycle : Pre-step to Krebs Cycle The Krebs Cycle (the boring part) : The Krebs Cycle (the boring part) Also known as the citric acid cycle, the Krebs cycle takes place in the mitochondrial matrix. This cycle is kicked off with the transfer of the two carbon part of acetyl CoA, to a four carbon compound. Quite a few chemical reactions occur, keeping the Krebs cycle very busy. Electrons transfer to the electron carrier molecules NAD+ and FAD. Chemical Reactions : Chemical Reactions Reactants and Products : Reactants and Products Reactants 3 NAD+ 1 FAD Citric Acid 1 ADP Products 3 NADH 1 FADH2 3 CO2 1 ATP Remember that there are two halves of the glucose molecule to process, so double these! The Krebs cycle occurs twice for each glucose molecule. Krebs Cycle : Krebs Cycle Electron Transport Chain (E.T.C.) : Electron Transport Chain (E.T.C.) E.T.C. occurs in the inner mitochondrial membrane. The energy carrier molecules we discovered earlier release their energy by transferring them to the large electron carrier proteins. Three of these five proteins are ion pumps. They use the energy from the carrier molecules to pump two hydrogen ions through the membrane.
