|
|
Term
| How are the smaller molecules used to build sugar for the Calvin- Benson cycle? |
|
Definition
| It uses ATP and reduces the power of electrons carried by NADPH |
|

|
Definition
|
|
Term
| What do plants do on hot, dry days to conserve H2O and what does this limit? |
|
Definition
| It closes the stomata, which conserves H2O, but limits photosynthesis |
|

|
Term
| What does Photorespiration consume and release? |
|
Definition
| Photorespiration consumes O2 and energy, and releases CO2 without producing ATP or SUger |
|
|
Term
| What are alternatice Mechanisms for CO2 fixation? |
|
Definition
- Minimizing photorespiration by concentraitng C02
- C2 plants
- Crassulacean Acid metabolism (CAM)
|
|
|
Term
|
Definition
| compartmentalization to 'pump' CO2 |
|
|
Term
| What happens with CAM (Crassulacean acid metabolism)? |
|
Definition
They open their stomata at night, incorporating CO2 into organic acids
Stomata close during the day, and CO2 is released from organic acids and used in the Calvin cycle |
