8.3 Two Photosystem Of Plants

Question 1

Photosystem ni apa?

Answer 1

Photosynthetic pigments yang arranged on thylakoid membranes

Question 2

What are the components of a photosystem? (Ada 2)

Answer 2

1. Rxn center
2. Light harvesting complexes

Question 3

A light harvesting complex consists of: (ada 3)

Answer 3

1. Chlorophyll a
2. Chlorophyll b
3. Carotenoids

Question 4

Light harvesting complexes are bound to ________

Answer 4

Proteins

Question 5

How does a rxn center work?
(Ada 4 points)

Answer 5

1. Accepts photon
2. Excites e- in special chlorophyll a molecule to higher E level
3. e- will be captured by the primary e- acceptor
4. then, the e- will be transferred to ETC

Question 6

Function of light harvesting complexes
( 1 function)

Answer 6

• Act as an antenna which absorbs photon and transmit it from molecule to molecule sampailah chlorophyll a at rxn center

At rxn center:
- primary e- acceptor accepts the excited electron from chlorophyll a

Question 7

Differentiate between photosystem II and photosystem I (ada 2 points each)

Answer 7

(tele!)

Question 8

Function of photosystem is to generate _____________

Answer 8

ATP and NADH

Question 9

Photosynthesis ada 2 stages”:

Answer 9

• Light Dependent Reaction
• Light Independent Reaction

Question 10

Light dependent reaction kat mana and produce apa?

Answer 10

• kat thylakoid membrane
• produce ATP + NADPH

Question 11

Light independent reaction kat mana and use apa?

Answer 11

• kat stroma
• uses ATP (from light dependent rxn) for carbon fixation
