6CO2 -> C6H12O6 (glucose)

Question 4

Oxidation reaction in photosynthesis

Answer 4

6H2O -> 6O2

Question 5

High energy molecules in Photosynthesis

Answer 5

Glucose and Water

Question 6

Site of light reactions

Answer 6

Thylakoids

Question 7

site of the Calvin cycle

Answer 7

Stroma

Question 8

What is the reducing agent used to synthesize carbohydrates from CO2

Answer 8

NADPH

Question 9

Why is an input of ATP Required for regeneration?

Answer 9

to regenerate RuBP during the Calvin Cycle

Question 10

What is Chlorophyll used for?

Answer 10

Harness E from the sun (breaks H2O molecules to use their electrons)

Question 11

The function of a photosystem

Answer 11

convert absorbed light energy into the movement of electrons

Question 12

Which photosystem comes first and why

Answer 12

Photosystem 2 because photosystem 1 was discovered first but photosystem 2 occurs first in the cycle

Question 13

What does photosystem 1 do

Answer 13

splits water to retrieve electrons for ATP synthesis

Question 14

What does photosystem 2 do

Answer 14

excited electrons to reduce NADP+

Question 15

What does Photosystem 2 do

Answer 15

reduces NADPH to NADP+

Question 16

What goes into producing 1 glucose

Answer 16

18 ATPs and 12 NADPH

Question 17

what is chemiosmosis

Answer 17

movement of protons down channel to generate ATP via ATP synthase

Question 18

Calvin’s cycle consists of

Answer 18

15 chemical reactions that synthesize carbohydrates from CO2

Question 19

first step of Calvin cycle

Answer 19

carboxylation (CO2 is added to RuBP)

Question 20

second step of Calvin cycle

Answer 20

reduction (energy and electrons from NADPH are transferred)

Question 21

third step of Calvin cycle

Answer 21

regeneration of RuBP

Question 22

What happens to excess carbohydrates

Answer 22

They are stored in the form of starch for energy when sunlight is absent

Question 23

What is the percentage of yield of photosynthesis?

Answer 23

4% of sunlight is transformed into carbohydrates
