24 Jun What are the three different metabolic pathways that are responsible

Question
1What are the three different metabolic pathways that are responsible for the production of ATP?

a/substrate inhibition, catabolism, and fermentation

b/glycolysis, the reactions on the electron transport chain, and the Krebs (citric acid) cycle

c/hydrolysis, active transport, and the light reactions

d/glycolysis, oxidation, and the Calvin cycle reactions

e/None of the above answer choices is correct.

2When energy is converted from one form to another,

a/some energy is converted to heat.

b/a small amount of energy is destroyed.

c/a small amount of energy is created.

d/the quantity of energy in the universe changes.

e/it becomes more useful to organisms for fueling cellular activity.

3The outputs of cellular respiration are

a/oxygen, water, and ATP.

b/oxygen, carbon dioxide, and ATP.

c/carbon dioxide, water, and oxygen.

d/carbon dioxide, water, and ATP.

e/oxygen and sugar.

4Photosynthesizing plants rely on water to

a/replace electrons that are excited by light energy and passed from molecule to molecule down an electron transport chain.

b/replenish oxygen molecules that are lost during photosynthesis.

c/provide the protons necessary to produce chlorophyll.

d/concentrate the beams of light hitting a leaf, focusing them on the reaction center.

e/serve as a high-energy electron carrier

5 In cellular respiration, energy-rich

a/carbohydrate molecules are oxidized to carbon dioxide and water.

b/fat molecules are oxidized to carbon dioxide and water.

c/sugar molecules are oxidized to carbon dioxide and water.

d/carbohydrate molecules are oxidized to carbon dioxide and oxygen.

e/Only the first, second, and third answer choices are correct.

6 If a thylakoid were punctured so that its interior was no longer separated from the stroma, which of the following processes would be affected most directly?

a/NADPH oxidation

b/ATP synthesis

c/flow of electrons from photosystem I to photosystem II

d/the splitting of water

e/chlorophyll’s energy absorption

The ultimate result of glycolysis is two molecules of

a/ethanol.

b/NAD+.

c/glucose.

d/pyruvate.

f/lactic acid.

7 Cyanide is such a deadly poison because it

a/blocks the passage of electrons to oxygen in the electron transport chain.

b/effectively halts the production of ATP within mitochondria.

c/breaks down the mitochondrial matrix.

d/facilitates rapid transfer of electrons to carrier molecules.

e/Both the first and second answer choices are correct.

8 To synthesize one glyceraldehyde 3-phosphate (G3P) molecule, the Calvin cycle has to fix three atoms of carbon from carbon dioxide to an organic molecule within the chloroplast. This process consumes how many molecules of ATP and NADPH, respectively, which were generated in the “photo” reactions?

a/3, 6

b/6, 8

c/9, 6

d/9, 9

e/9, 12

9 When a photon strikes a molecule, the photon may do any of the following EXCEPT

a/bounce off the molecule.

b/pass through the molecule.

c/be absorbed by the molecule.

d/be oxidized by an electron from the valence shell of the molecule.

e/All of the above are possible outcomes of a photon striking a molecule.

10 In animals, exertion without sufficient oxygen leads to the production of

a/pyruvate.

b/NADH.

c/lactic acid.

d/ethanol.

e/water.

11 Carotenoids

a/are the stacks of thylakoid membranes in a chloroplast.

b/are more abundant in leaves in the fall than either chlorophyll a or b.

c/absorb red, orange, and yellow wavelengths of light.

d/reflect blue-green and blue-violent wavelengths of light.

e/are the site of photosynthesis in a plant cell.

12 Chlorophyll’s most important role during photosynthesis is

a/keeping the leaves of plants green.

b/converting light energy from the Sun into chemical energy.

c/capturing electrons that can, in turn, be used by carotenoids.

d/turning into a molecule of ATP upon being struck by sunlight.

May be I miss an option with last one
