| Question | Answer |
|---|---|
| Glycolosis net input | glucose nad adp |
| Glycolosis net ouput | Pysruvate atp nadh |
| Glycolosis not input or output | Oxygen Coenzyme A Carbon Dioxide acetyl CoA |
| Acetyl CoA Formation net input | Pyrucate NAD Coenzyme A |
| Acetyl CoA Formation net ouput | Acetyl CoA Carbon Dioxide NADH |
| Acetyl CoA Formation not input or output | Glucose Cardon Dioxide ATP ADP |
| Citric Acid Cycle net input | NAD acetyl CoA ADP |
| Citric Acid Cycle net output | Carbon Dioxide ATP NADH coenzyme A |
| Citric Acid Cycle not input or output | Glucose Pyruvate Oxygen |
| Oxidative Phosphorylation net input | NADH Oxygen ADP |
| Oxidative net output | ATP NAD Water |
| Oxidative not input or output | Glucose carbon dioxide acetyl CoA coenzyme A pyruvate |
| Glycolysis happens | in cytosol |
| Acetyl CoA formation happens | in mitochondrial matrix |
| Critic acid cycle happens in | mitochondrial matrix |
| Oxidative phosphorylation happens | in inner mitochondrial membrane |
| When a compound donates (loses) electrons, that compound becomes oxidized | Such a compound is often referred to as an electron donor |
| When a compound accepts (gains) electrons, that compound becomes reduced | Such a compound is often referred to as electron accepter |
| In glycolysis, the carbon-containing compound that functions as the electron donor is | glucose |
| Once the electron donor in glycolysis gives up its electrons, it is oxidized to a compound called | pyruvate |
| NAD+ is the compound that functions as the electron acceptor | in glycolysis |
| The reduced form of the electron in glycolysis is | NADH |
| Among the products of glycolysis, which compounds contain energy that can be used by other biological reactions? | pyruvate, ATP, and NADH |
| How many carbons in acetyl CoA | 2 |
| How many carbons in citrate and isocitrate | 6 |
| How many carbons in alpha ketoglutarate | 5 |
| How many carbons in sussinyl CoA, succinate, oxaloacetate | 6 |
| Pyruvate oxidized to | CO2 |
| Nad reduced to | NADH |
| FAD reduced to | FADH2 |
| Why is the citric acid cycle a cyclic pathway rather than a linear pathway? | It is easier to remove electrons and produce CO2 from compounds with three or more carbon atoms than from a two-carbon compound such as acetyl CoA |
| In mitochondrial electron transport, what is the direct role of O2? | to function as the final electron acceptor in the electron transport chain |
| How would anaerobic conditions (when no O2 is present) affect the rate of electron transport and ATP production during oxidative phosphorylation? (Note that you should not consider the effect on ATP synthesis in glycolysis or the citric acid cycle) | Both electron transport and ATP synthesis would stop |
| NADH and FADH2 are both electron carriers that donate their electrons to the electron transport chain, The electrons ultimately reduce O2 to water in the final step of electron transport, the amount of ATP made by electrons from an NADH molecule is greate | Fewer protons are pumped across the inner mitochondrial membrane when FADH2 is the electron donor than when NADH is the electron donor |
| Suppose that a cell’s demand for ATP suddenly exceeds its supply of ATP from cellular respiration, Which statement correctly describes how this increased demand would lead to an increased rate of ATP production? | ATP levels would fall at first, decreasing the inhibition of PFK and increasing the rate of ATP production |
| Remains the same for gramicin | rate of oxygen uptake, proton pumping rate, e- transport rate |
| Decreases for gramicin | size of proton gradient, rate of ATP synthesis |
