1
Q
What’s the photosynthesis equation
A
Water + CO2 = o2 + sugar
2
Q
Where is light absorbed in a cell
A
In the chlorophyll found in the cholroplast
3
Q
What’s the name of stage 1 of photosynthesis and what happens
A
Light reaction
Light from the sun is captured in the chlorophyll and converted into chemical energy to make ATP
water is split to make hydrogen and oxygen
Oxygen is realised in the atmosphere whole hydrogen and ATP is passed onto stage 2
4
Q
What’s the name of stage 2 of photosynthesis and what happens
A
Carbon fixation
It’s a enzyme controlled reaction where hydrogen and ATP from light reaction combine with carbon dioxide to make sugar
5
Q
What can sugar do made by photosynthesis
A
1 used in respiration
2 turned into starch
3 use as cellulose to make cell walls
