Question

1.

The production of _______________ generated billions of years ago by a key by-product of photosynthesis allowed the earth to filter out harmful radiation, allowing life to live on land.

Select one:

amino acids

ozone (O3)

carbohydrates

H2O

triglycerides

2.

In aerobic respiration, most of the ATP are produced here:

Select one:

via fermentation

glycolysis

Krebs Cycle

electron transport chain

conversion of pyruvate to acetyl Co-A

3.

The process of fermentation does not produce as much ATP as aerobic respiration because:

Select one:

oxidation-reduction reactions do not occur

NADP is not used in the reactions

glycolysis does not occur

glucose is not used

O2 is not involved

4.

In aerobic respiration this would not happen without O2 present:

Select one:

Glycolysis

Production of NADH

Production of glyceraldehyde 3-phosphate

Production of H2O

Production of FADH2

5.

In the energy investment stage of glycolysis, ATP is used to convert glucose into _________.

Select one:

fructose-1,6 biphosphate

acetyl CoA

FADH2

citric acid

ribulose biphosphate

6.

In the energy liberation step of glycolysis, these molecules are produced.

Select one:

ATP and NADH

NADH and FADH2

O2 and ATP

ATP and FADH2

CO2 and ATP

Answer 1

1) Ozone is formed by addition of oxygen molecule and nascent oxygen.Oxygen molecule is produced by photosynthesis.

2) kreb cycle :- produce 34 ATP .

Glycolysis produce only 2 ATP.

3) oxygen is not involved ( because without oxygen oxidative phosphorylation don't occur ). Oxidative phosphorylation produce 34 ATP and glycolysis produce only 2 ATP ( NAD+ reduced to NADH).

4) D

production of FADH2 via kreb cycle . NADH is also produced by Glycolysis.Glucose molecule is broken down into glyceraldehyde 3 phosphate.

5) A

Fructose 1,6 bis - phosphate is produced via energy investment phase ( by investing 2ATP ).

6)A

ATP and NADH is liberated via energy liberation phase of glycolysis
