Section 1What is the Calvin Cycle?
Where does it take place?
What is Carbon Fixation?
|What is the product of carbon fixation?|
What is the product of Reduction?
What is Regeneration?
|How many turns of the Cycle to make CO2|
|How many turns to make 1 G3P?|
|What is photorespiration?||uses up ATP - reverse photosynthesis declines / undoes Carbon Fixation|
|What is Rubisco?||CO2 fixing enzyme with 8 active sites for CO2 fixation|
|Why is Rubisco inefficient?||Catalyzes bith 02 AND CO2 - Oxygen competes slows CO2 reduction|
|When is Carbon Fixation favoured over photorespiration?||+CO2 HIGH and O2 is low|
|How is CO2 delivered to Rubisco?||Gas exchange where CO2 enter pores|
|How is a pore created?||2 guard cells change shape to create a pore when CO2 is low|
|When are stomata open?||During the day, closed at night to prevent water evaporation.|
|What happens during the stomata stays open?||Allows CO2 to diffuse in inside lead and then ECF fluid|
|What is C4 Photosynthesis?||Incorporate CO2 into 4 carbon organic acids into C4 pathway|
|What does PEP do?||PEP carboxylase fixes CO2 in meophyll cells|
|What is the purpose of C4 photosynthesis?||Limits damaging effects of photorespiration|
|What is a CAM plant?||PLants temporarily fix CO2 to organic acids to Crassulacean Acid Metabolism|
|What is the difference between C4 plants and CAM plants?||C4: reactions catalyzed by PEP & Rubisco seperated in space. CAM - reactions are separated in TIME.|
