2.

1 point

What is the correct equation for cellular respiration

6co2+6h2o--> 6co2+6h2o+energy

6co2+6h2o+energy --> 6co2+ ch12o6

1 point

during lactic acid fermentation

oxygen is required

NAD+ is regenerated, allowing glycolysis to continue

13.

1 point

cellular respiration is called an aerobic process because it requires

light

exercise

glucose

oxygen

17.

1 point

the krebs cycle starts with

pyruvic acid and yields carbon dioxide

glucose and yields 32 ATP's

lactic acid and yields carbon dioxide

18.

1 point

which of the following passes high energy electrons into the electron transport chain

citric acid

19.

1 point

each pair of high energy electrons that moves down the electron transport chain provides enough energy to

convert 3 ADP molecules into 3 ATP molecules

break down glucose into pyruvic acid

convert carbon dioxide into water molecules

transport water molecules across the membrane

20.

1 point

the energy of the electrons passing along the electron transport chain is used to make

alcohol

lactic acid

21.

1 point

breathing heavily after running a race is your bodies way of

repaying an oxygen debt

recharging the electron transport chain

making more citric acid

restarting glycolysis

22.

1 point

when the body needs to exercise for longer than 90 seconds, it generates ATP carrying out

alcoholic acid fermentation

cellular respiration

glycolysis

lactic acid fermentation

23.

1 point
