Exam 2 Part 4

Question 1

B- ox materials produced/used

Answer 1

2 ATP used to start cycle
1 NADH/cycle
1 FADH2/cycle
– 1 FADH2 per dB

Question 2

Electron transport chain NADH ATP production

Answer 2

2 1/2 NADH needed for 1 ATP

Question 3

Electron transport chain FADH2 ATP production

Answer 3

1 1/2 FADH2 for 1 ATP

Question 4

gana

Answer 4

stacks of thylakoids

Question 5

NADPH

Answer 5

used in photosynthesis

synthesizing e- transfer molecule

Question 6

light reactions

Answer 6

Stage 1 of photosynthesis

uses photosystems to make energy

Question 7

dark reactions

Answer 7

Stage 2 of photsynthesis
Calvin cycle (C fixation) to make sugar

Question 8

thylakoid

Answer 8

3rd bilayer in chloroplast - where business takes places

Question 9

photosystem

Answer 9

used in light reactions - like a satellite dish for light
have light-harvesting antenna complexes
energy is transferred from one chlorophyll molecule to another and reaches the reaction center

Question 10

chlorophyll special pair

Answer 10

in reaction center of photosystem
energy boots off e- and breaks the pair
special pair wants the e- back, so strips e- off H2O and releases oxygen

Question 11

moving electrons and pumping protons in chloroplast

Answer 11

photosystem II pumps electons across to generate O2 and H+ on thylakoid space side
photosystem I pumps e- across and NADPH are produced
ATP synthase uses the generated H+ gradient to make ATP in the stroma

Question 12

Calvin Cycle

Answer 12

(C fixation)

harnesses the light energy to make things like sugar (cellulose)

Question 13

Calvin Cycle net products

Answer 13

3 CO2
1 G3P
– 9 ATP (loss)
– 6 NADPH (loss)

Question 14

G3P

Answer 14

glyceraldehyde 3-phosphate

produced by Calvin cycle and can be used to make sugar, fats, and amino acids
