Photosynthesis Flashcards
0
Q
What is the first stage of photosynthesis? Describe it
A
Photolysis- the splitting of water into hydrogen and oxygen
H2O-> hydrogen + oxygen
H2O is split using the light energy and ADP + Pi-> ATP cycle
The oxygen diffuses out pores called stomata
1
Q
What is the simple word equation for photosynthesis?
A
Co2 + water -> glucose + oxygen
2
Q
What is the second stage of photosynthesis? Describe it
A
Carbon fixation
Co2 + hydrogen-> glucose
Hydrogen is used from the first stage
The ATP is broken down to ADP + Pi, changing the Co2 + hydrogen to Glucose
3
Q
What is the glucose used for?
A
Starch store
Cellulose- structure in the cell wall
4
Q
What are some limiting factors of photosynthesis?
A
Carbon dioxide concentration
Light intensity
Temperature
