Adenosine triphosphate
How does ATP work
The last phosphate is broken off and releases energy
Rate of photosynthesis with increasing CO2
Rate of photosynthesis with increasing light
Rate of photosynthesis with increasing pH
Rate of photosynthesis with increasing temperature
Rate of photosynthesis with different colors of light
Primary photosynthetic pigment
Chlorophyll
What colors does chlorophyll absorb best?
Red and blue
Root functions
Absorb water, nutrients, & oxygen
Glucose formula
C6H12O6
General photosynthesis equation
CO2 + H2O —-> C6H12O6 + O2
Where does oxygen come from?
Water
Where do plants get their mass?
CO2 in the air
What is the purpose of the light reactions?
Capture and store energy into ATP and NADPH
What is the purpose of the Calvin cycle?
Convert CO2 into glucose
