Biol 231 exam 2
Locations and input/output
| Question | Answer |
|---|---|
| photons absorbed and funneled | within thylakoid membrane |
| H20--> 1/2O2 + 2H + 2e- | thylakoid lumen, inner face of thylakoid membrane |
| O2 generated, H+ accumulates | thylakoid lumen |
| e- excited and transported | within thylakoid membrane |
| H+ pumped | across thylakoid membrane from Stroma--> lumen |
| NADP --> NADPH | stroma, at outer face of thylakoid membrane |
| H+ flow thru ATP synthase | across thylakoid membrane from lumen--> stroma |
| ADP + Pi --> ATP (via ATP synthase) | stroma, at outer face of thylakoid membrane |
| CO2 fixed into carbohydrate | stroma |
| NADPH --> NADP | stroma |
| glucose synthesis | stroma and cytoplasm |
| TCA | Input: pyruvate output: CO2, GTP, high energy electrons, associated with a carrier molecule. Location: mitochondrial matrix |
| Glycolysis | Input: glucose, ATP Output: 2 x pyruvate, 2ATP, 2NADPH Location: cytosol |
| Electron Transport | Input: high energy electrons, associated with a carrier molecule, O2 Output: potential energy of a H+ gradient Location: IMM |
| Mitochondrial ATP synthesis | Input: potential energy of H+ gradient Output: ATP Location: IMS, IMM and Matrix (assocaited with the inner mitochondrial membrane) |
| Stop Codons | UAA, UAG, UGA |
| Depolarization | The Na channel opens and Na flows into cell (influx) |
| Repolarization | Voltage gated K channels are open and K flows out of the cell. The Na channels have closed |
| Refractory Period | prevents an action potential that is being propagated along an axon toward the synapse form changing directions by Na quickly close ad cannot be opened again for few msec. |
