What enzyme combines RuBP with CO2 in the 'ideal' Calvin Cycle
RuBP
3GP
Rubisco
Mesophyll
Which of the following can attach to rubisco (multiple choice)
RuBP
CO2
O2
H20
Which of the following describes the MAIN advantage of C4 Photosynthesis
It uses 4 carbon chains, which produce more glucose
Its stomata in the mesophyll cell is not always open, leading to lower water loss
The mesophyll cell containing the stomata is separated from where the calvin cycle takes place
It occurs in the stomata, rather than outside the cholorplast
The main way that water escapes the plant is
Dehydration
Maceration
Evaporation
Transpiration
When RuBP is combined with CO2, it forms
2 x phosphoglycerate
Phosphoglycerate and glycerophosphate
Glucose and RuBP
G3P and glucose
The O2 produced by photosynthesis is produced during the (a) reaction
The glucose produced in photosynthesis is produced by the (a) reaction
During CAM photosynthesis, CO2 is stored in the form of (a) in the vacuole
When is the stomata open in CAM photosynthesis (Multiple Choice)
Daytime
Night-time
What environments are ideal for CAM photosynthesis (Multiple choice)
Hot days
Dry
Marsh
Cool Nights
How are CAM and C4 photosynthesis similar?
Both are associated with desert environments
Both attempt to avoid photorespiration
Both only open their stomata only when they need to
Both use the Calvin cycle
What would happen if too much hot air is let into the plant through the stomata
Rubisco would become more efficient
Rubisco would break down
The light-dependent reaction would increase
Rubisco would become more efficient to a certain point until it breaks down.
