| Question | Answer |
| Respiration equation | Oxygen+Glucose ----- Water+carbon dioxide(+energy) O2 + C6H1206 ---- H2O + CO2 (+ATP) |
| Where does glycolysis occur | in the cytoplasm |
| what are the FOUR stages of glycolysis | stage 1: activation of glucose by phosphorylation stage 2: splitting of phosphorylated glucose stage 3: oxidation of triose phosphate stage 4; production of ATP |
| How many ATP are produced during glycolysis | net gain of 2 |
| How and where does the pyruvate go to after glycolysis and how? | It is actively transported to the matrix of the mitochondria |
| The equation of the link reaction | pyruvate + NAD + CoA ---- acetyl CoA + NADH + C02 |
| What does the krebs cycle involve and where | located in the matrix of the mitochondria the krebs cycle involved a series of oxidation and reduction reactions |
| Krebs cycle | coenzymes involved FAD and NAD |
| Where is the electron transport chain located? | the inner folded membrane of the mitochondria the cristae |
| State the importance of coenzymes in the ETC | The NADH and FADH 'donate' protons and electrons |
| State the importance of electrons in the ETC | Electrons are passed down carrier molecules in a series of oxidation-reduction reactions releasing energy |
| state the importance of oxygen | O2 acts as the final acceptor of H+ ions this is so there is not a 'back up' of ions |
