Where does the light-dependent reaction take place?
Thylakoid membrane
1 of 20
What is a photosystem?
protein and photosynthetic pigment structure found in the thylakoid membrane
2 of 20
what is an electron carrier?
proteins that transfer electrons
3 of 20
what is an electron transport chain?
chain of proteins which excited electrons flow
4 of 20
Where is PSII? what takes place there
granal lamellae/ photolysis - produces 2H and 2e and 02
5 of 20
what is photolysis?
splitting of a water molecule in the presence of light energy
6 of 20
Outline the light-dependent reaction
PSII -> excited e accepted by e acceptor carried along etc (movement of e releases nrg pumps H across mem) H diffuse thru channel protein activating ATP synthase/ protons and e then accepted by coenzyme NADP
7 of 20
What is non-cyclic phosphorylation?
involves PSI/II / produces ATP NADPH O2/ water e donor NADP e acceptor
8 of 20
What is cyclic phosphorylation?
PSI only/ e lost carried back to PSI700 by e carriers/ produces ATP only/ chlorophyll and PSI e donor and acceptor
9 of 20
What are the products of the light dependent stage?
ATP / NADPH / O2
10 of 20
What is chemiosmosis?
movement of H+ across a membrane which generates ATP
11 of 20
Where does the light-independent stage take place?
stroma

Briefly outline the Calvin Cycle
1. formation of GP/ 2. Formation of TP/ 3. Regeration of RuBP
13 of 20
What is GP? how is it produced
Glycerate 3-phosphate/ co2 enters via stomata diffuses into stoma/ combined with RuBP/ produces unstable 6C which breaks down into 2GP/ catalysed by rubisco
