O2 consumption by amino acids and branched-chain acids in Arabidopsis
Data represent the mean ± se of at least three mitochondria preparations and are expressed as nanomoles O2 per minute per milligram of protein.
| Substrate | O2 Consumption Rate |
|---|---|
| Pyruvate | 152 ± 10.0 |
| α-Ketoglutarate | 125 ± 15.7 |
| Leu | 10 ± 3.8 |
| Ile | 2.1 ± 1.0 |
| Val | 17 ± 5.2 |
| α-Ketoisovaleric acid (Leu) | 0.3 ± 2.0 |
| α-Keto-β-methylvaleric acid (Ile) | 0 ± 1.2 |
| α-Ketoisovaleric acid (Val) | 3.4 ± 1.1 |
