| Question | Answer |
|---|---|
| Catabolic Pathway | release stored energy by breaking down complex molecules. |
| Electron transfer | energy is harvested from electrons and used to produce ATP |
| Enzymes | lower the energy required for the reaction to take place. (speed up chemical reactions) |
| Exergonic reaction | release of energy |
| Aerobic Respiration | consumes organic molecules, uses O2 as final acceptor and yields ATP |
| Fermentation | partial degradation of sugars that occurs without O2 |
| Substrate level phosphorylation | formation of ATP by transfer of a phosphate group to ADP by a substrate |
| Oxidative phosphorylation | production of ATP is powered by redox reactions of the electron transport chain |
| Principle of Redox | chemical reactions that transfer electrons between reactions are called redox reactions. |
| Oxidation | Substance loses electrons in a redox reaction |
| Reduction | A substance gains electrons. Positive charge is reduced in redox reaction |
| Reducing agent | electron donor |
| Oxidation agent | electron receptor |
| Anaerobic Respiration | pathway in which inorganic molecules other than O2 accept electrons at the end of ETC |
