What is a photosynthetic pigment? give examples
coloured substance that absorbs light energy needed for photosynthesis, chlorophyll a and b and carotene
1 of 7
What is ATP produced from? How is it produced?
phosphorylation of ADP and an inorganic phosphate group, ATP synthase enzyme, H+ ions into thylakoid, concentration gradient so move into stroma, movement provides energy to combine ADP and Pi
2 of 7
Where do the two stages of photosynthesis take place? what are there products?
light dependant in thylakoid membrane- ATP and reduced NADP, light independent in the stroma-organic stubstances
3 of 7
Explain the calvin cycle for the light independent reaction
Rubisco catalyses carboxylation of RuBP to for 2 GP, ATP and reduced NADP reduce GP to 2 TP, some is used to make organic substances, rest recycled-converted to RuBP
4 of 7
What photosystems does non-cyclic phosphorylation use? how does it work?
1 and 2, light energy excites electrons (2) which move along electron transport chain (1) lose energy which is used to make ATP, electrons to NADP to form reduced NADP
5 of 7
What is photolysis and what is it used for?
splitting water with light, produce H+ ions for making ATP and electrons to replace those lost in photosystem 2
6 of 7
What happens during cyclic phosphorylation?
light excited electrons in photosystem 1, move up energy level then passed back by electron carriers, lose energy to create ATP (only)
