Photosynthesis

Question 1

Photosynthesis converts CO2 + H2O + sunlight into

Answer 1

Carbohydrates + O2

Question 2

Photosynthesis is done by:

Answer 2

Plants, bacteria + algae

Question 3

What are the two stages of Photosynthesis?

Answer 3

• Light-dependent

- Dark Reactions

Question 4

A Light-dependent requires

Answer 4

Photons + water

Question 5

What do Light-dependent reactions produce?

Answer 5

ATP + NADPH (reducing agent)

Question 6

Dark reactions do not depend on

Answer 6

Photons

Question 7

What is another name for the Dark reactions?

Answer 7

Calvin Cycle

Question 8

The Calvin Cycle takes in the ATP + NADPH produced by the light-dependent reactions and forms

Answer 8

G3P

Question 9

What acts as a source of Carbons for the Calvin Cycle?

Answer 9

CO2

Question 10

Light-dependent use light energy and water to produce

Answer 10

ATP

Question 11

Light-dependent reactions reduce NADP+ into

Answer 11

NADPH

Question 12

Light-dependent reactions form

Answer 12

ATP, NADPH + O2

Question 13

Light-dependent reactions happen in the

Answer 13

Thylakoid membrane of the chloroplast

Question 14

Photon energy excites electrons of

Answer 14

P680

Question 15

P680 is a strong oxidizing agent that gets its electrons from

Answer 15

Water

Question 16

NADPH Production starts at

Answer 16

P700

Question 17

The excited electron of P680 then goes to

Answer 17

P700, reducing NADP+ into NADPH

Question 18

What happens as electrons move to lower energy states?

Answer 18

Hydrogen ions are pumped through the membrane, fueling the production of ATP via the synthase

Question 19

How does the Calvin Cycle produce sugar?

Answer 19

It takes light-dependent products and use with CO2

Question 20

The fluid in the chloroplast is called the

Stroma

Question 21

Stroma has folded stacks called

Answer 21

Thylakoids

Question 22

Carbon Fixation is done by the

Answer 22

Byproducts of light-dependent reactions, or during the Calvin Cycle

Question 23

Carbon Fixation is done in the

Answer 23

Stroma

Question 24

RuBisCo is an enzyme which

Answer 24

Catalyzes reaction between Co2 and RuBP without using ATP

In higher temperatures, RuBisCo has a higher affinity for

Answer 26

O2

Question 27

At milder temperatures, RuBisCo has a higher affinity for
