Clicker Question Review

Question 1

ATP is made in what stages of cell respiration?

Answer 1

Glycolysis, Citric Acid Cycle, and ETC

Question 2

Chemiosmosis occurs in _____

Answer 2

Cell Respiration(oxidative phosphorylation) and Photosynthesis(photophosphorylation).

Question 3

C6H12O6 + 6O2 -> 6 CO2 +6H2O + ATP + Heat

Answer 3

Cell Respiration summary formula.

Question 4

Reduction gains or loses an electron?

Answer 4

gains an electron.

Oxidation loses an electron.

Follow H atom(removed H = oxidized. Added H = reduced)

Question 5

Fermenting utilizes_____

Answer 5

Only glycolysis.

Makes 2 ATP.

Lactic Acid Fermentation: pyruvate is converted to lactic acid regenerating NAD+ to continue glycolysis.

Alcohol fermentation: pyruvate is first converted to acetaldehyde(making CO2) and then to ethanol, regenerating NAD+

Question 6

Purpose of Pre-citric acid step

Answer 6

converts pyruvate to acetyl Co-A required to enter citric acid cycle.

Question 7

Autotrophs and producers are associated with_____

Answer 7

Photosynthesis.

Able to turn inorganic carbon into organic molecules(fixing carbon)

Question 8

During the _____ of the light reactions, NAPDH, ATP, and O2 are produced and both photosystem I and photosystem II are used.

Answer 8

Non-cyclic electron flow.

Cyclic flow only PS I is used and only ATP is produced.

Question 9

Oxidized, photosynthesis

Answer 9

NADP+

Question 10

Oxidized, CR

Answer 10

NAD+

Question 11

Reduced, CR

Answer 11

NADH

Question 12

Reduced, CR again

Answer 12

FADH2

Question 13

Reduced, Photosynthesis

Answer 13

NADPH

Question 14

Where does the Oxygen we breath come from and where is it used?

Answer 14

Water is split during light reactions of photosynthesis.

ETC uses O2 as the final electron acceptor so that chemiosmosis can generate a H+ gradient to make ATP.

Question 15

Do plants have cell respiration?

Answer 15

Yes.

Plants use photosynthesis to make organic molecules which can then be broken down by cell respiration to make ATP.

Question 16

Fe+Cu^2+ -> Fe^2+ + Cu

who got reduced?

Answer 16

Cu.

Fe oxidized

Question 17

Photocynthesis: Who gets reduced?

CO2 + 12H2O + Light Energy -> C6H12O6 + 6O2 + 6H2O

Answer 17

CO2 gaines H and thus its electrons and becomes reduced.

Water is oxidized.

Question 18

Summary of cell respiration:

Answer 18

The oxidation of food molecules requiring oxygen to gain energy.

Question 19

Do prokaryotes undergo glycolysis?

Answer 19

Yes. All organisms do it. Mitochondria is not required.

Question 20

Does cell respiration turn oxygen into carbon dioxide?

Answer 20

No.

CO2 is formed from the breakdown of organic molecules such as glucose.

Question 21

What is the purpose of fermentation reactions?

Answer 21

To regenerate NAD+ so glycolysis can continue.

Question 22

What is the plants cells version of cell respiration?(photosynthesis?)

Answer 22

No.

Plants do cell respiration just like animals.

Question 23

Over 24 hour period you measure oxygen in a lake with plants and fish.

Answer 23

More oxygen measured during the day than at night(photosynthesis shuts down without light)

Question 24

Seeds grow by___

Answer 24

cell respiration NOT photosynthesis.

Question 25

Photosynthesis summary equation

Answer 25

6CO2 + 12H2O + Light energy -> C6H12O6 + 6O2 + 6 H2O

Question 26

What is the worst color of light to grow plants in?

Answer 26

Green(we see green because it is reflected)

Question 27

The oxygen we breath comes from:

Answer 27

H2O during photosynthesis

Question 28

Does the Calvin Cycle needs light?

Answer 28

Sort of.

Light reactions need light to power PS II and I but if those do not run then the Calvin Cycle can not get what it needs from PS I.

Question 29

What has higher oxygen content? Fake plant tank or real plants

Answer 29

Real plants will produce more oxygen(no bubbler required)
