Photosynthesis Flashcards
1
Q
What is the equation for photosynthesis?
A
6CO2 + 6H2O + Energy –> C6H12O6 + 6O2
2
Q
what is photoionisation?
A
2 electrons in cholorophyll are booster to a higher energy level and then taken up by an electron carrier
3
Q
Is the cholorophyll molecule oxidised or reduced during photoionisation?
A
oxidised
4
Q
Is the electron carrier oxidised or reduced during photoionisation?
A
reduced
5
Q
what is phosphorylation?
A
electrons are passed along a transfer chain releasing energy which is used to synthesise ATP.
6
Q
what is broken down in photolysis?
A
H20
7
Q
What are the products of photolysis?
A
H+, e- and 1/2O2
8
Q
What’s Chemiosmosis?
A
the energy from photolysis is used to pump H+ from stoma into thylakoid through ATP synthase channels forming ATP.
