Chapter 20 Flashcards
1
Q
What molecule blocks the active site of Rubisco?
A
Ribulose 1,5-bisphosphate
2
Q
What is needed for one complete cycle of the Calvin cycle (produce glucose)?
A
6 CO2 + 18 ATP + 12 NADPH + 12H + 12H20
3
Q
What is needed to produce 1 glyceraldehyde 3-phosphate?
A
3 CO2 + 9 ATP + 6 NADPH + 6H + 6H20
4
Q
What does the Pi-triose phosphate antiporter do?
A
Transports Pi into the stroma and dihydroxy-acetone phosphate into the cytosol.
5
Q
what would happen to an inhibited Pi-triose phosphate antiporter?
A
Pi in the chloroplast would be depleted and slow ATP synthesis. CO2 would assimilate into starch.
6
Q
What is produced when rubisco reacts with oxygen?
A
2-phosphoglycolate
