Calvin cycle
Stages of the Calvin cycle
#1 carbon fixation #2 reduction #3 regeneration
For every three molecules do CO2 that enter the Calvin cycle, the cycle produces six molecules of...
3-PGA
How many molecules of ATP and NADPH are used in a single turn of the Calvin cycle?
9 molecules of ATP and 6 molecules of NADPH
How do CAM plants differ from both C3 and C4 plants?
CAM plants open their stomata at night
Using (CH2O) as general formula for a carbohydrate, write the simplest overall equation for photosynthesis
CO2 + H2O (light energy) (CH2O) + O2
Calvin cycle
Combines carbon from carbon dioxide in the air and uses the chemical energy in ATP and NADPH to make glucose
C4 pathway
Enables certain plants to fix CO2 into four carbon compounds
As light intensity increases, the rate of photosynthesis...
Initially increases and then levels off
Stoma
Major passageways in the form of small pores that are often found on the underside of plant leaves
Carbon fixation
Occurs when carbon atoms from CO2 from the atmosphere are branded into organic compounds
CAM pathway
Plants fix carbon through this pathway; stands for crassulacen acid metabolism
Why does the rate of photosynthesis increase, peak and then decrease as temperature increases?
The rate peaks at a certain temp. at which many of the enzymes that catalyze reactions become ineffective
Stomata can open and close in response to changes in the CO2 concentration inside the leaf. Would you expect stomata to open or close if the CO2 concentration decreased?
The stomata would open, allowing more CO2 to enter the leaf, thus stimulating photosynthesis
Organic compounds that can be made from the products of the Calvin cycle include...
Carbohydrates, amino acids and lipids
C3 and C4 plants differ in terms of the number of...
Carbon atoms in the compound that CO2 is initially incorporated into
The Calvin cycle begins when CO2 combines with a five carbon carbohydrate called...
