|
Both cellular respiration and fermentation begin with what molecule?
|
Glucose
|
|
What reactant needed for cellular respiration is absent from the fermentation reaction?
|
Oxygen
|
|
What gas do organisms give off when they carry out cellular respiration?
|
Carbon Dioxide
|
|
Both fermentation and cellular respiration provide what molecule needed by cells?
|
ATP (Adenosine Triphosphate)
|
|
Do plant cells or animal cells carry on cellular respiration?
|
Both
|
|
Which process, fermentation or cellular respiration, results in an end product that contains C-H bonds?
|
Fermentation
|
|
Name the device that can measure the amount of gas given off by yeast.
|
Respriometer
|
|
Yeast cells carry out fermentation when they are supplied with what type of molecule?
|
Ethanol
|
|
During the fermentation experiment, the gas bubble got larger. What gas was causing this increase?
|
Release of Carbon Dioxide (CO2)
|
|
What role was played by KOH in the soybean experiment?
|
Absorbtion
|
|
In the germinating seed experiment, what do you call the tube that contains only glass beads?
|
Thermobarometer
|
|
What gas is being taken up when the marker in the side arm of a respirometer moves toward a tube that contains germinating seeds?
|
Oxygen, Nitrogen, and Carbon Dioxide
|
|
If you performed the cellular respiration experiment without soaking the cotton with KOH, what results would you predict? Why?
|
No net change for vial 1 in addition to 2.
Why? The carbon dioxide given off in vial 1 will obscure the uptake of oxygen in that vial. |
|
Why is it reasonable that, of the three sugars (glucose, fructose, and sucrose),
glucose would result in the most activity during the fermentation experiment? |
Glucose is
the sugar ordinarily acted on by yeast. |
