Photosythesis Flashcards
What is the word equation for photosynthesis?
Carbon dioxide + water → glucose + oxygen
What is the balanced symbol equation for photosynthesis?
CO2 + H20 → C6H1206 + 02
Where does the energy for photosynthesis come from?
The sun
What type of reaction is photosynthesis?
Endothermic (takes heat in)
Where is the energy stored in the plant?
In chlorophyll found in chloroplats
What is the energy converted to?
Chemical energy in form as glucose
What is the limiting factor?
The factor that stops the reaction
As the temperature increases…
More energy is given to the reaction
At what temperature does the rate drop to zero?
45°C
Why does the rate drop to zero at 45°C?
The enzymes controlling the reaction are destroyed
As the CO2 concentration increases…
The rate increases
When the increase in CO2 has no effect…
C02 is no longer the limiting factor
As light intensity increases…
Rate increases as has more energy
When more light has no effect…
Light is no longer the limiting factor
What does the graph for light intensity look like?
Steady increase then levels off
