1

Goals of photosynthesis

- convert light energy to chemical energy (ATP)
- produce reducing equivalents (NADPH)
- convert CO2 to sugar (Carbon Fixation)

2

what is the source of electrons?

water

3

antenna pigments

capable of absorbing light but cannot convert it to chemical energy - pass it on to chlorophyll a pair

4

Photosystem I

energizes and transfers e- that are donated to NADP+

5

Photosystem II

oxidizes water molecules and donates the energized e- to e- carriers that eventually reduce PSI

6

cytochrome b6f complex

passes e- from PSII to PSI

7

Z scheme reaction

H2O -> PSII ->PQ -> cyt bf -> PC -> PSI -> Fd -> FNR -> NADP+

8

how many steps are there in water-oxidizing clock

5 oxidation states

9

Manganese Cluster

stabilizer protein that allows for series of oxidation to occur next to PSII

10

first and last e- carriers?

first: chlorophyll a
last: ferredoxin (2 pathways)

11

Noncyclic e- transport

FNR to make NADPH

12

Cyclic e- transport

PQR drives ATP synthesis without making NADPH
