Worksheet time: 10mins
What is consumed in aerobic respiration?
Oxygen
Nitrogen
Carbon Dioxide
Water
Leaves
The primary purpose of cellular respiration in living organisms is to…
Remove excess carbon dioxide from the cells.
Create water by combining Oxygen and Hydrogen ions.
Produce biologically useful energy in the form of ATP
Produce molecules that can be used in the electron transport system.
Create larger complex molecules such as carbohydrates, proteins, and Lipids
The products of glycolysis include two pyruvate molecules and…
Two molecules of oxygen
Two net molecules of ATP
One molecule of glucose
Four ATP and two molecules of NADH
Two molecules of NADH and two ATP
Fermentation is an anaerobic process that recycles NAD+ from the NADH that is produced in glycolysis. The conversion of NADH to NAD+ is critical, as it allows glycolysis to continue to change glucose to pyruvate.
If oxygen is not present in sufficient quality, pyruvate molecules are converted into…
Amino Acids or Fatty Acids
Carbon Dioxide and Water
CO2 or O2
Ethanol or Lactic Acid
acetyl-CoA and citric acid
Prior to entering the Krebs cycle, each pyruvate molecule loses electrons, hydrogen ions, and a carbon, forming an energy rich molecule of…
NAD+
NADH
FADH2
CO2
acetyl-CoA
What is the NADH and FADH2 formed in the Krebs Cycle primary function?
Remove the waste product CO2 from the system.
Transfer electrons to the electron transport chain
Provide the energy to synthesize acetyl-CoA
Catalyze the production of ATP from ADP
Facilitate the production of water by combining hydrogen ions with O2
After the Krebs Cycle only a small portion of the energy of glucose has been converted. At this point what is the majority of usable energy is contained in?
NADH and FADH2
Pyruvate
Acetyl-CoA
CO2
Citric Acid
How do fermentation reactions contribute to the continued production of ATP in the absence of oxygen?
Splitting carbon dioxide and releasing additional oxygen.
Moving acetyl-CoA molecules to the Krebs cycle.
Recycling NADH molecules to NAD+ molecules.
Producing enzymes that convert ADP to ATP
Breaking down ethanol or lactic acid to carbon dioxide and water.

Cellular respiration uses one molecule of glucose to produce?
26-28 ATP
NADH
2-4 ATP
CO2
30-32 ATP
Which of the following occurs in both fermentation and aerobic cellular respiration?
glycolysis
ATP is synthesized from ADP and Inorganic phosphate.
Photosynthesis
sleeping

What is the distinction between anaerobic respiration and fermentation?
One is big
One is small
ETC is used in anaerobic respiration but not in fermentation
ETC is used in aerobic respiration but not fermentation
All of the above
Which of the following correctly compares the processes involved in aerobic and anaerobic respiration?
Glycolysis takes place in the cytosol, while the Krebs Cycle and ETC take place in the mitochondria.
Glycolysis takes place in the mitochondrial matrix, while the Krebs cycle and ETC take place in the intermembrane space.
Glycolysis takes place in the mitochondria, while the Krebs cycle takes place in the cytosol.
