|
Plants photosynthesize |
Only in light but respiratory in light and dark |
|
|
Calvin cycle function |
using atp and nadph made during light reactions. Carbon is reduced in the _____ and sugar is made |
|
|
Molecule that is the main product of Calvin cycle |
G3p |
|
|
Stroma |
Where the Calvin cycle takes place |
|
|
C4 plants occur more commonly in desert conditions because |
They can fix carbon at lower concentrations that develop when stomata are closed |
|
|
Relationship between photosynthesis and respiration |
P*** stores energy in complex organic molecules and R**** releases energy from complex organic molocules. |
|
|
Electrons loss of energy as they pass through system of electron carriers associated with psii |
Is used to establish an maintain a proton gradient |
|
|
Product of light reaction of photosynthesis |
Oxygen atp and nadph |
|
|
Linear electron flow |
Ps II only ●oxidize water ●Reduction of electron transport chain between systems Ps I only ●oxidation of electron transport chain between systems ●Reduction of nadp+ Both ●Light absorption ●Reduction of primary electron receptor. |
|
|
Energy requirement for linear electron flow |
None for water to p680+ Pq to p700+ Fd to nadp+ Energy required for P680 to Pq (plastoquinone) P700 to Fd (ferredoxin) |
|
|
Photosynthesis similarities of C4 and CAM plants |
In both Rubicon is not used to fix carbon initially |
|
|
CAM plants keep stomata closed in the daytime, thus reducing loss of water. They can do this because they_ |
fix C02 into organic acids during the night |
