What is the CO2 acceptor in a C3 plant?

Ribulose 1,5 bisphosphate
What is the primary CO2 acceptor in a C3 plant?

Ribulose 1,5 bisphosphate
What is the primary CO2 acceptor in a C4 plant?

Phosphoenol pyruvate
What is the name of the enzyme that catalyses incorporporation of CO2 into Ribulose 1,5 bisphosphate

Rubisco
Which cell type in a C plant contains Rubisco?

Bundle sheath cells
Which photosystem contains the water-splitting activity?

Photosystem II
Which cell type in a C4 plant contains photosystem II?

Mesophyll cells
How many moles NADPH and ATP are required for the fixation of 1 mol CO2 in a C3 plant?

2 mol NADPH and 3 mol ATP
How many moles of NADPH and ATP are required for the fixation of 1 mol CO2 in a C4 plant?

2 moles NADPH and 5 moles ATP
What is the function of cyclic photophosphorylation?

To generate additional ATP
Name the two compounds photosystem I can transfer electrons to.

NADPH-reductase and Ferredoxin
What is the principal difference between a C4 and a CAM plant?

C4 plant - spatial separation between energy production(light reaction) nd Calvin cycle (dark reaction). In a CAM plant both processes are separated in time.
What is the difference between the Calvin cycle of a C3 and a C4 plant?

No principal difference in biochemistry. In a C4 plant the Calvin cycle is carried out only in bundle sheath cells and thus separated from the light reaction in Mesophyll cells.
