In cellular respiration, ___ ATP molecules must be input to initiate the process of glycolysis. A) 2 **
B) 3
C) 5
D) 6
Glycolysis is the process where cells split the sugar glucose to make 2 ATP. Both prokaryotes and eukaryotes carry out glycolysis. Where (what location) does glycolysis occur in the eukaryotic cell pictured here?
A) 2 X
B) 5 X
C) 9 X
D) 11 Correct
An experimental design was set up by biology students to observe cellular respiration by aerobic bacteria in a closed culture. A measured amount of glucose was added to the culture at the beginning of the experiment with no subsequent glucose added later. The students measured carbon dioxide and oxygen levels using electronic probes. The initial oxygen level was 600 parts per million (ppm) and the initial carbon dioxide level was 120 ppm. Which data is consistent with the process of cellular respiration occurring by the bacteria in the culture if tested one hour after the initial reading in the experiment?
A) Oxygen- 720 ppm
Carbon dioxide- 80 ppm
B) Oxygen- 600 ppm
Carbon dioxide- 120 ppm
C) Oxygen- 200 ppm
Carbon dioxide- 520 ppm **
D) Oxygen- 800 ppm
Carbon dioxide- 720 ppm

Yeast is a fungus commonly used in baking that makes dough rise through the process of fermentation. For fermentation to occur yeast requires fuel in the form of sugar. The fermentation rate varies depending upon the type of sugar used. You and your lab mates tested the fermentation rate of yeast using different sugars. Glucose and fructose are both monosaccharides while sucrose, lactose, and fructose are disaccharides. What can NOT be concluded based on the data collected?
A) Glucose has the highest rate of fermentation. X
B) Fructose and maltose have similar rates of fermentation. X
C) Lactose is not an effective sugar source for fermentation. X
D) Disaccharides have a higher rate of fermentation than monosaccharides. Correct
The metabolic reaction that occurs in the cells of all living organisms is:

C6H12O6 + 6O2 → 6H2O + 6CO2

Which process involves a reaction similar to this reaction?
A) burning of fossil fuels Correct
B) reduction of carbon compoundsX
C) formation of lactic acid from glucose X
D) transfer of energy into high energy compounds like ATP X
