Photosynthesis

Question 1

First stage light dependent stage

Answer 1

Photon hits photosystem 2 which releases 2 electrons

Regains electrons through photolysis of water

Question 2

Second step in light dependent stage

Answer 2

Electrons travel down ETC which transports 2 H+ into thylakoid space
Electrons transferred to photosystem 1

Question 3

Third step in light dependent stage

Answer 3

Photon hits photosystem 1 which transfers 2 electrons to NADP which becomes reduced

Question 4

How is ATP produced

Answer 4

H+ gradient in thylakoid space pass through ATP synthase producing ATP as H+ go into stroma

Question 5

Cyclic photophosphorylation

Answer 5

Photon hits Photosystem 1 which releases electrons back to ETC (which transports H+ into thylakoid space) before returning to Photosystem 1

Question 6

First step in Light independent stage

Answer 6

6 RuBP with 6CO2 form 6 RuBisCO

Question 7

Second stage of light independent stage

Answer 7

6 RuBisCO forms 12 GP

Question 8

Third stage of light independent stage

Answer 8

12 GP + 12 ATP + 24H* (from reduced NADP) forms 12 TP and 12 NADP

Question 9

Forth stage of light independent stage

Answer 9

10 TP + 5 ATP forms 6 RuBP

2 TP form amino acids, fatty acids and/or glycerol

Question 10

Fluid within chloroplasts

Answer 10

Stroma

Question 11

Stack name

Answer 11

Granum

Question 12

Individual units of granum

Answer 12

Thylakoids

Question 13

Link between structures

Answer 13

Intergranal lamellae
