Cellular Respiration
| Question | Answer |
|---|---|
| What is cellular Respiration? Where does it occur? | energy is extracted from glucose to make ATP |
| What is required for cellular respiration to occur? | glucose |
| What are the products for cellular respiration? | Carbon Dioxide + water+ ATP |
| Cellular respiration = aerobic process What does that mean | process that uses oxygen |
| Reduction | occurs when electrons are added |
| Oxidation | electrons are removed |
| Reduction +Oxidation | Redox reactions |
| What two important coenzymes are reduced during cellular respiration | NAD AND FAD |
| NAD AND FAD | Carry potential energy to electron transport chain |
| Four major steps of cellular respiration | Glycolosis Preparatory Reactions Krebs Cycle Electron Transport Chain |
| What step of cellular respiration occur in the cytoplasm | Glycolosis |
| Does glucose contain more or less free energy than pyruvate | More. That is then broken down and releases energy |
| What does the energy investment step of glycolysis involve | 6 carbon glucose molecules |
| The oxidation of G3P to 1,3 results in the production of what form of potential energy | high energy electron |
| What is substrate phosphorylation | enzyme transfers directly from a substrate to ADP |
| In phosphorylation how many ATP are produced in glucose? | |
| What is the final product of glycolysis of one glucose molecule | pyruvate |
| Gross production of ATP ,NADH ,FADH during glycolysis | |
| What is the net production of ATP, NADH, FADH during glycolysis | 2 ATP 2NADH |
| What occurs after glycolysis if oxygen is not available | fermentation |
| where does fermentation occur in the cell | cytoplasm |
| How many ATP are produced per glucose molecule in fermentation | |
| After glycolysis if oxygen is available where does it occur | mitochondra for aerobic process |
| where does the citric acid cycle take place | matrix mitochondria |
| what is the first step of citirc acid cycle | acetyl CoA joins with 4 carbon |
| What molecule is oxidized during citric acid cyle to reduce NAD to NADh | Acetyl CoA |
