| Glycolysis | EMP (Embden Meyerhof Parnas) pathway
Occurs in cytoplasm Common step in both aerobic and anaerobic respiration Hexose is converted to two molecules of pyruvate |
| Aerobic respiration | 1. Glycolysis (Cytoplasm)
2. Pyruvate to acetyl CoA by pyretic dehydrogenase (mitochondrial matrix) 3. TCA or Krebs cycle (mitochondrial matrix) |
| Alcoholic Fermentation | Pyruvic acid to ethanol and CO2
Enzymes- pyruvic acid decarboxylase and alcohol dehydrogenase |
| Lactic acid fermentation | Pyruvic acid to lactic acid
In muscles and some bacteria Enzyme- lactate dehydrogenase |
| Tricarboxylic acid cycle (TCA) | Hans Krebs (Krebs cycle)
Citric acid cycle- In the first step OAA reacts with acetyl CoA to produce citric acid |
| Net gain of ATP per glucose in aerobic respiration | 36 or 38 ATP
Glycolysis- 6 or 8 ATP (2 ATP and 2 NADH) Transition reaction- 6 ATP (2 NADH) TCA- 24 ATP (2 GTP, 6 NADH, 2 FADH2) |
| Decarboxylation reactions | Pyruvate to acetyl CoA
Isocitrate to πΌ-ketoglutarate πΌ-ketoglutarate to succinyl CoA |
| Substrate level phosphorylation (ATP production) | Glycolysis- 1,3-bisphosphoglyceric acid to PGA
PEP to Pyruvic acid TCA- succinyl CoA to Succinate (GTP is produced) |
| Electron transport system (ETS) | Inner mitochondrial membrane
Complex I- NADH dehydrogenase (FMN, Fe-S) Complex II- Succinate dehydrogenase (FAD, Fe-S) Complex III- Cytochrome bc1 Complex IV- Cytochrome c oxidase (cyt a, a3, two Cu) Complex V- ATP synthase (F0, F1) |
| Mobile electron carrier | Cytochrome C and ubiquinone (UQ) |
| Respiratory quotient | Carbohydrate- 1
Fat- 0.7 Protein- 0.9 |
| Net gain of ATP in fermentation | 2 ATP |
