Glucose
Water
How many cycles are needed to produce 1 molecule of glucose?
1 cycle
3 cycles
6 cycles
12 cycles
Which part of the Calvin cycle uses energy from ATP?
Reduction of GP to triose phosphate
RuBP reacting with carbon dioxide
Production of water
Oxidation of RuBP
The enzyme (a) is needed for RuBP to react with carbon dioxide.
How many carbon atoms are in RuBP?
4
6
5
3
What does RuBP stand for?
rubiscon bisphosphate
rubisco enzyme phosphate
Are you biology pro
ribulose bisphosphate
Put the steps of the Link Reaction into the correct order in which they occur.
RuBP reacts with CO2
...this is catalysed by the enzyme rubisco
GP is reduced using NADPH and ATP
This produces NADP which can be used in the LDR
Triose phosphate can be recycled into RuBP, or go towards making glucose.
Match the reactants with their products
ATP
Unstable 6C molecule
2 x Glycerate 3-phosphate reduced into...
ADP + Pi
Carbon dioxide + RuBP
2 x Glycerate 3-phosphate
NADPH
NADP+
Unstable 6C molecule
2 x triose phosphate
How many molecules of glucose are produced for each cycle of the Calvin cycle?
1/6
1
6
0.6
What is the majority of the triose phosphate produced in the Calvin cycle used for?
to produce glucose
recycled for into reactants for the LDR
recycled into RuBP
to produce pyruvate
After 12 GP molecules are created, 10 are used to regenerate _________, while the other 2 are used to create __________.
What happens to the majority of the GP molecules in the last step of the light independent reactions?
How many GP molecules make one molecule of glucose?
