2: 1. Glycolysis
3: MAKING MEMORIES | o-o-o-o-o-o Glucose | 2 Pyruvate | o-o-o o-o-o | ~ 2 Pyruvate ~ 2 NADH ~2 ATP | End with a net of:
4: Where they go: | o-o-o | NADH | to be used by the cell
6: 1.5 Pyruvate Oxidation | 1. One carbon breaks off to form CO2 with two oxygens in the area
7: 2. NAD+ combines with H+ and is reduced to NADH | 3. Coenzyme A (from a B vitamin) combines with the remaining 2 carbons | Product: Acetyl CoA goes to Krebs Cycle
8: 2. Krebs Cycle | Another name for the Krebs Cycle is the Citric Acid cycle because Acetyl CoA combines with a 4-carbon compound called oxaloacetic acid to form citric acid
9: End with a net of: | ~4 CO2 ~6 NADH ~2 FADH ~2 ATP
10: 3. Oxidative Phosphorylation: Electron Transport Chain and Chemiosmosis | Net: | ETC: electrons pass from electron carriers until they reach Oxygen atoms. 2 electrons combine with the 2 Oxygens, and 2 Hydrogens that happen to be floating in the matrix- produces H2O
11: Chemiosmosis: There is a higher concentration of H+ ions outside of the matrix than inside, so they want to "come" into the matrix. However, the membrane is not permeable to H+ ions, so they must be transported through with a protein that synthesizes ATP. The energy given off when H+ goes through the protein fuels the phosphorylation of ADP to form ATP.
