Cellular Respiration

Front 1

glycolosis begins with

Back 1

1 6 carbon molecule
2 molecules ATP
2 inorganic P04- molecules

Front 2

glycolosis ends with

Back 2

2 3 carbon pyruvate mlecules
4 APT molecules (net gain 2)
2 NADH molecules

Front 3

If oxygen is present in glycolosis:

Back 3

NADH goes to ETC,
pyruvic acid continues to the transition rxn

Front 4

Transition rxn begins with

Back 4

1 3 carbon molecules of pyruvic acid
co enzyme

Front 5

transition rxn ends with

Back 5

1 2 carbon molecules of acetyl coA
1 NADH molecule
1 CO2 molecle

Front 6

After transition rxn...

Back 6

Acytyl CoA moves through mitochondrial membrane, COA breaks off and returns to cytoplasm, acetyl molecle combines with oxaloacetic acid to form citric acid

Front 7

Krebs cycle begins with

Back 7

1 acetyl molecule

Front 8

Krebs cycle ends with

Back 8

2 co2 molecules
1 fadh molecule
3 nadh molecules
1 atp molecule

Front 9

Where do all nadh molecules originate from?

Back 9

2 from glycolosis
2 from transition rxn
6 from krebs cycle

Front 10

how many ATP generated from each nadh and fadh

Back 10

3 from each nadh
2 from each fadh

Front 11

if oxygen is not present, what happens?

Back 11

pyruvic acid converts to lactic acid

Front 12

fermentation ends with

Back 12

3 carbon molecule of lactic acid
net gain of2 atp from glycolosis

Front 13

what materials are needed by a cell to produce ATP

Back 13

ADP phosphate, energy source, appropriate e nzyme

Front 14

how does ATP and ADP differ?

Back 14

phosphate groups- ATP has one more phoshate andhigh energy bond, when phosphate is removed high amoumt of energy is created

Front 15

describe glucose (how many atoms of C H AND O

Back 15

6C
12H
6O
much mor energy than one molece oc co2

Front 16

describe oxidation in terms of oxidation, energy

Back 16

oxidized molecule loses energy (loss of electrons) when molecule is reduced, it gains energy from electron it gains

Front 17

describe function of NAD

Back 17

sites for temporaty storeage of energy and for transportation of energy, energy is in form of hydrogen, so reduced form is called NADH

Front 18

break down of glucose results in formation of _______ during this process some hydrogens are released from glucose and are picked up by molecule called __

Back 18

pyruvic acid, NAD

Front 19

end products of fermentation include

Back 19

ATP C02 ethyl alchohol

Front 20

compare oxidized form of NAD with reduced form

Back 20

oxidized form - NAD
reduced form- NADH, more energy, added hydrogen

Front 21

how many acetate groups are formed by glucose during respiration?

Back 21

two
each acetate contains two carbon atoms
two co2 molecules are released

Front 22

the initial events of the Krebs Cycle involve the combination of a four carbon molecule with acetate to produce a molecule that is named __and contains __ atoms

Back 22

citric acid, carbon atoms

Front 23

in the ETC molecules of _____ are produced by ______ of carrerier molecules and the subsequient removeal of enregy fromthe atomicstructures called ______

Back 23

adenosine triphosphate
produced by oxidation
from electrons

Front 24

aerobic respiration of one molecule of glucose result in net gain of how many ATP

Back 24

approx 36

Front 25

low energy electonr released at the end of ETC combine with ions of ___, tese newly formed atoms of molecules then combine with atoms of _____ to produce molecules of ___ one of the end prodcts of aerobic respiration

Back 25

hydrogen
oxygen
water

Front 26

primary function of respriation is

Back 26

transfer energy from storage molecules such as glucose to usable molecuels ATP

Front 27

what happens to a cell that cannot respire?

Back 27

cannot produce molecules of ATP, die
