honors bio cellular respiration test

when blood gulcose levels decrease (as between meals) what reserves will be used first?

glycogen

what metabolic pathway is common to all cells

glycolysis

a chemist has discovered a drug that blocks the enzyme adlolase. he wants to use the drug to kill bacteria in people with infections. The reason that he cannot do this is because

human cells also undergo glycolysis, so the drug might poison them

hydrolysis

glucose is converted into glycogen primarily in the

liver

substrate level phosphorylation

occurs during glycolysis

what process is transition from glycolysis to the Krebs Cycle?

acetyl CoA formation

which of the following molecules can be used as a substrate for cellular respiration? -glucose -fats -proteins -polysaccarides

all of the above

-electron transport and chemiosmosis-ATP,H2O -cirtric acid cycle -CO2,NADH,FADH2,ATP -formation of acetyl CoA- acetyl CoA, CO2 -glycolysis-pyruvic acid, ATP, NADH which process doesn't match the products

all the processes match the products

in an experiment, mice were fed glucose containing a small amount of radioactive oxygen, The mice were closely monitored, and a few minutes radioactive oxygen atoms showed up in

carbon dioxide

cell respiration is most accurallty described as a _____________process

catabolic

-are generally exergonic -usually produces ATP -are part of metabolism -may produce monosaccharides from polysaccharides all describe what

catabolic reactions

the splitting of molecules into smaller components is refried to as:

catabolism

most of the ATP made during cellular respiration occurs during a process known as

chemiosmiosis

one product of the initial (first) reaction of the herbs cycle is:

citric acid

select the process that are matched with the INCORRECT amount of ATP produced by that process per glucose molecule - glycolysis-- 2ATP(net) -citric acid cycle--4ATP -electron transport chain--32ATP -alcohol fermentation--0ATP -lactate fermentaion--0ATP

citric acid cycle--4ATP

in eukaryotes, glycolysis occurs in the:

cytosol

during the citric acid cycle, each acetyl group entering the cycle yields:

1ATP, 2NADH,and 2CO2

glycolysis yields a net energy profit of ______ ATP molecules per molecule of glucose

2

in glycolysis, glucose receives two phosphate groups from ______, thus forming fructose-1, 6-biphosphate

ATP

fermentation is essentially glycolysis plus an extra step in which pyruvic acid is reduced to form lactic acid or alcohol and carbon dioxide, This last step

extracts no ATP form pyruvic acid

the regenerated molecule in the Kerbs cycle is

oxaloacetic acid

In aerobic respiration, the electrons associated with the hydrogen atoms in glucose are transferred to:

oxygen in a series of steps

how would you rid your muscles of the painful lactic acid build- up after strenuous exercise?

participate in light exercise while breathing deeply

lactic acid production muscle cells is:

permanent, and due to oxygen deficiency

in glycolysis, a six-carbon glucose molecule is converted to two three- carbon molecules of:

pyruvic acid

during aerobic respiration, oxygen is:

reduced

a glucose molecule that is metabolized via aerobic respiration has been completely broken down and released as CO2 by the end of:

the citric acid cycle

the transfer of electrons from glucose to oxygen during aerobic respiration takes place in a stepwise fashion through a number of intermediates rather than by direct transfer. This is because:

the energy of the electrons can be used to make ATP

The role of the oxygen molecules required for aerobic respiration is:

to accept the low energy electrons at the end of the electron transport chain

considering only glycolysis and the conversion of pyretic acid molecules to acetyl CoA molecules, how many NADH molecules will be produced from one glucose molecule?

two

oxidative decarboxylation of two pryruvic acid yields:

two acetyl groups +two CO2

in another experiment mice were allowed to beathe oxygen gas laced radioactive oxygen. In this experiment the radioactive oxygen atoms quickly showed up in

water

aerobic respiration is classified as :

a redox process

name an anaerobic pathway

fermentation

glycolysis -mitochondrion formation of acetyl CoA-cytosol citric acid cycle -mitochondria electron transport -mitochondria which process does NOT match the location in skeletal muscle?

glycolysis -mitochondrion

NADH and FADH2 are products of:

reduction reactions

what step of the Kerb's cycle directly produces a molecule of ATP?

succinate >fumaric acid

when molecules are broken apart in respiration

the energy realsed in respiration is channeled into molecules of ATP

ubiquinol or coenzyme Q

transfers electrons

in the Kerbs acid cycle, two acetyl CoA molecules are metabolized to

4CO2+6NADH+2FADA2+2ATP

in glycolysis, fructose-1, 6-bisphosphate splits, forming two molecules of:

PGAL

-occur as part of the citric acid cycle -produce CO2 that is then exhaled via breathing -involve the removal of a carbon dioxide from a substrate -are one type of general reaction that occurs during aerobic respiration All describe what?

Decarboxylations
