Identify the incorrect statement regarding the TCA (Krebs) cycle:
| 1. | The TCA cycle begins with the condensation of the acetyl group with oxaloacetic acid (OAA) to form citric acid, catalyzed by citrate synthase. |
| 2. | The TCA cycle involves three steps where NAD⁺ is reduced to NADH + H⁺ and one step where FAD⁺ is reduced to FADH₂. |
| 3. | During the conversion of succinyl-CoA to succinic acid, ATP is synthesized directly through substrate-level phosphorylation. |
| 4. | The continuous functioning of the TCA cycle depends on the regeneration of oxaloacetic acid as well as NAD⁺ and FAD⁺ from NADH and FADH₂. |
