Module 11 Set 4
| Question | Answer |
|---|---|
| TCA cycle oxidation steps | form NADH and FADH2 |
| TCA cycle completes | substrate-level phosphorylation |
| TCA cycle energy drives | condensation of acetyl group with oxaloacetate |
| TCA cycle oxidation and decarboxylation steps | form NADH + H+ and CO2 |
| TCA cycle performs | complete oxidation and degradation |
| TCA Cycle step 1: | Cycle begins by adding C2 acetyl group to C4 molecule, forming citrate; also called the citric acid cycle. |
| TCA Cycle step 2: | Acetyl group is then oxidized to two molecules of CO2. |
| TCA Cycle step 3: | During the oxidation process, most electrons (e) are accepted by NAD+ and NADH is formed. |
| TCA Cycle step 4: | In one instance, electrons are taken by FAD, which becomes FADH2. |
| TCA Cycle step 5: | NADH and FADH2 carry these electrons to electron transport system. |
| TCA Cycle step 6: | Some energy released is used to synthesize ATP by substrate-level phosphorylation |
| for each acetyl-CoA molecule oxidized, TCA cycle generates 2 molecules of | CO2 |
| for each acetyl-CoA molecule oxidized, TCA cycle generates 3 molecules of | NADH |
| for each acetyl-CoA molecule oxidized, TCA cycle generates one | FADH2 and GTP |
