Answer 8

Photon

Question 9

A photosystem is composed of what 2 parts?

Answer 9

Reaction center complex, light harvesting complex

Question 10

——- ——— complex funnels energy of photons to the ——– ——– complex

Answer 10

1) light harvesting complex, 2) reaction center complex

Question 11

When a special pair of ——— molecules absorb energy, one of its electrons is boosted to a higher energy level and transferred to the ——–

Answer 11

1)reaction center cholorphyll a. 2)primary electron acceptor

Question 12

After reaching the primary electron acceptor, linear electron flow produces —–, —–, ——

Answer 12

NADPH, ATP, 02

Question 13

NADPH, ATP, and 02 are produced from —-

Answer 13

linear electron flow

Question 14

there is 8 steps to linear electron flow, Summarize the first 5:

Answer 14

1)p680 cholrophyll a gets excited and produces electron
2)Electron produced transferred from P680 to primary electron acceptor (now p680+)
3) Splitting of water produces 2 electrons, 2 h+, one o2 atom. 2 electrons are supplied to p680+, electrons get transferred to primary electron acceptor
4)each electron gets passed from the primary electron acceptor in photosystem 2, to the Photosystem one via electron transport chain
5)the exergonic fall of electrons during the journey thru the etc provides synthesis of ATP. H+ is pumped into thylokoid space which will be used later in chemosmois.

Question 15

there are 8 steps to linear electron flow, summarize the lase 3 (6-8)

Answer 15

6)meanwhile in photosystem one, a pigment 700 gets exicted and its electrons are transferred to the primary electron acceptor. p700 turns into p700+, and can accept the electrons that passed thru the etc from ps 2, to 1.
7)electrons produced from p700+ are passed down to photosystem ones electron acceptor, and down a second etc thru a protien called ferredoxin (FD)
8)after Fd gets used the electrons are transferred to the enzyme NADP+ reductase which catalyzes the transfer of electrons into NADPH

Question 16

Like cellular respirtaion, the diffusion of —- down atp synthase forms atp

Answer 16

h+
