Photosynthesis and respiration review
| Term | Definition |
|---|---|
| Steps of aerobic respiration | Glycolysis, link rxn, Kerbs (citric acid) cycle, and oxidative phosphorylation |
| hydrogen/ electron carriers of aerobic respiration | NAD , reduced NAD (NADH) and FAD, reduced FAD (FADH2) |
| Glycolysis location | in cell's cytoplasm |
| Link rxn location | in matrix of mitochondria (via active transport) |
| Kerbs cycle location | in matrix of mitochondria |
| oxidative phosphorylation and electron transport chain location | in inner mitochondria membrane |
| Glycolysis and ATP | 2 ATP required, but 4 total ATP produced (net= +2) |
| Glycolysis and NAD | 2 NAD are reduced= 2 NADH |
| Glycolysis: what happens to Glucose | split into 2 pyruvate molecules |
| Glycolysis: phosporylation | when phosphate is added to ADP= ATP |
| Glycolysis: what are the products and where do they go | products= ATP and NADH they go to Link rxn |
| Link Rxn: Decarboxylated | 1 carbon removed, given off as CO2 |
| Link Rxn: Dehydrognated | NAD picks up a H |
| Link Rxn: what happens to pyruvate | comined with coenzyme A to make acetyl CoA |
| Link Rxn: what are the products and where do they go | products: acetyl CoA and NADH they go to Kerbs cycle |
| Kerbs Cycle: How many turns for each glucose | 2X b/c glucose is split into 2 pyruvate molecues |
| Kerbs Cycle: Acetyl CoA combines with and makes | Combines with: oxalocetate (4c) Makes: citrate (6c) |
| Kerbs Cycle: Citrate is decarboxylated | 2X (loses 2 CO2) |
| Kerbs Cycle: Citrate is dehydrogenated | by NAD and FAD. They become reduced NAD and FAD |
| Kerbs Cycle: how many ATP generated | 1 |
| Kerbs Cycle: Oxaloactate is regenerated to | be ready to combine with acetyl CoA again |
| Kerbs Cycle: final product tally | 2CO2, 1 reduced FAD, 3 reduced NAD, 1 ATP |
| Kerbs Cycle: most important part | loading H's on FAD and NAD to bring to oxidative phosphorylation and e- transport chain |
