2. Plants get their carbon from the __________________.
3. Photosynthesis occurs in two steps, the second is the _____________________.
4. RuBP contains __________ carbons.
5. The enzyme, _________________________ builds an initial 6 carbon sequence.
6. This sequence split into two short chains called _________.
7. NADPH transfers a __________________ to those molecules, they become G3P.
