Photosynthesis

Question 1

Thylakoid

Answer 1

where light reactions take place

Question 2

Light harvesting complex

Answer 2

where the pigments are located that absorb light energy

Question 3

Reaction center complex

Answer 3

where chlorophyll a transfers electrons to the electron acceptor

Question 4

Photosystem 2

Answer 4

uses water to replace the P680 chlorophyll’s electrons and transfers electrons to PS 1

Question 5

Photosystem 1

Answer 5

uses electrons from PS 2 to replace P700 chlorophyll’s lost electrons and sends it electrons to NADP to produce NADPH

Question 6

Ferrodoxin

Answer 6

carries electrons from PS 1 to NADP

Question 7

Calvin cycle: Carbon fixation

Answer 7

fixes a carbon from CO2 onto a 5 carbon chain, which breaks into 2 3-carbon chains

Question 8

Calvin cycle: Reduction

Answer 8

NADPH donates electrons to the 3 carbon chain to make G3P

Question 9

G3P

Answer 9

supercharged molecule used for energy

Question 10

Calvin cycle: Regeneration

Answer 10

a process requiring ATP to form a new 5-carbon chain to out of extra G3P molecules so the Calvin cycle can repeat

Question 11

Number of 5-carbon sugars, G3P molecules reused, and G3P molecules produced

Answer 11

3 5-carbon molecules, 5 G3P molecules are reused and 1 G3P molecule is produced

Question 12

C3 plants

Answer 12

fix carbon into 3 carbon chains

Question 13

C4 plants

Answer 13

fix carbon into 4-carbon chains so that CO2 can be provided with the help of ATP when the stomata are closed

Question 14

CAM plants

Answer 14

open stomata at night and fix carbon into 4-carbon chains so that ATP can supply CO2 during the day
