better Module 5

Question 1

what happens in PTS II?

Answer 1

electrons in chain, O and H from H₂O released

Question 2

What happens in ETC of light reactions?

Answer 2

electrons go down chain, H+ ions go through membrane into thylakoid

Question 3

What happens in PTS I?

Answer 3

re-energize electrons, through ETC again, get NADPH

Question 4

What happens in the H+ movement and ATP formation of light reactions?

Answer 4

from charge difference, H+ ions go through ATP synthase, spinning it to catch ADP to make into ATP

Question 5

What happens in first part of Calvin cycle?

Answer 5

CO₂ in cycle, combines to get 12 3-carbon molecules

Question 6

What happens in the second part of Calvin cycle?

Answer 6

ATP and NADPH convert 3-carbon molecules to higher-energy forms, cycle restarts

Question 7

What are the products and reactants of light reactions?

Answer 7

6H₂O —> 6O₂

Question 8

What are the products and reactants of Calvin cycle?

Answer 8

6CO₂ —> glucose

Question 9

What carriers do light reactions make?

Answer 9

ATP, NADPH

Question 10

What carriers does Calvin cycle make?

Answer 10

9 ADP, 6 NADP+

Question 11

What makes up ATP?

Answer 11

Phosphate group, adenosine, ribose

Question 12

Where is PTS?

Answer 12

chloroplast

Question 13

What is PTS energy source?

Answer 13

sunlight

Question 14

Purpose of PTS

Answer 14

capture sun’s energy, store it in form of glucose

Question 15

What happens in the ATP production of glycolysis?

Answer 15

2ATP molecules start glycolysis

Question 16

What happens in NADH production of glycolysis?

Answer 16

remove 4 electrons; 2 go to NAD+ to make NADH and 2 go to ADP to make ATP

Question 17

What is the net products of glycolysis?

Answer 17

2 ATP, 2 pyruvic acids, NADH

Question 18

What happens in Citric acid production in Kreb’s cycle?

Answer 18

1 pyruvic acid carbon is made into CO₂. Other 2 pyruvic acid carbons make acetic acid. Acetic acid + coenzyme A = acetyl CoA. acetyl CoA adds acetyl to molecule to make citrus

Question 19

What happens during energy extraction in Kreb’s cycle?

Answer 19

Citric acid broken into 4-carbon molecule, and 2 CO₂ released. Electrons added to electron carriers

Question 20

How many Kreb’s cycles from 1 glucose?

Answer 20

2 cycles/1 glucose

Question 21

How many ATP from each Kreb’s cycle?

Answer 21

1ATP/1 cycle

Question 22

Net products of Kreb’s cycle

Answer 22

3 NADH, 2 ATP, CO₂, FADH2

Question 23

What happens during electron transport of electron transport/energy synthesis?

Answer 23

electrons passed through etc to enzyme at end of chain. Enzyme makes H₂O, H₂O is released. As passed through chain, H+ ions go through membrane inside thylakoid, making it positive

Question 24

What happens during ATP synthesis in electron transport/ATP synthesis?

Answer 24

change difference makes H+ go through ATP synthase, synthase spins and collects ADP. ADP and phosphate group combined in synthase, makes ATP

Question 25

Net reactants from cellular respiration?

Answer 25

36-38 ATP, 6 CO₂, 6 H₂O

Question 26

Purpose of cellular respiration?

Answer 26

Break down glucose to release stored energy in form of ATP.

Question 27

Location of cellular respiration

Answer 27

cytoplasm and mitochondria

Question 28

energy source of cellular respiration

Answer 28

glucose
