Term
| in 3HP -- is combined with -- to produce -- which is immediately processed to -- for -- |
|
Definition
| Inorganic bicarbonate is combined with both NADPH and ATP and produces glyoxylate which is the direct product but is immediately converted to pyruvate. Pyruvate is processed further for biosynthetic purposes. |
