| Question | Answer |
|---|---|
| Define atp | ATP is the mian supplier of metabolic energy in living cells. it is a high-energy compuind that is central to all that takes place during metabolism |
| What enzyme is used to breakdown ATP? | ATPase |
| What chemical reaction happens in the fibres of the muscles to resythesise ATP? | Phosphocreatine |
| What enzyme is used to brekdown phosphocreatine? | Creatine Kinase |
| How long can the ATP-PCr system be used? | 8-10 seconds |
| What energy source is used to take part in low intensity exercise? | Fats and Carbohydrates |
| What is the difference between the energy release in energy sources? | Fats have a slow release of energy Carbohyrates have a slow release of energy |
| What is Anaerobic Glycolysis? | Glucose is brokn down into pyruvic acid, which in turn then produces lactic acid. |
| What is beta oxidation? | The breakdown of fats into tri-glycerides |
| What is the Krebs cycle? | The oxidation of acetyl-coenzyme-A |
| What is the Electron transport chain? | A series of chemical reactions where hydrogen is oxidised to water and produces large amounts of ATP |
| Whyare carbohydrates used in high intensity exercise? | Because fats cannot be burned without the presence of oxygen. |
