Question8Lactic Acid Fermentation occurs in:

AnswerMuscle cells

Question9Glycolysis provides a cell with a net

gain of:

Answer2 ATP

Question10How many ATP are produced at the end of

cellular respiration?

Answer36

Question11What does NADH do?

AnswerCarries electrons from Glycolysis to the Kreb

cycle. Then NADH and FADH2 carry them to the Electron Transport Chain.

Question12While investigating yeast respiration, a

researcher detect ethanol in the yeast culture. Which molecules does the yeast culture also contain?

A) Lactic Acid and ATPB)Oxygen and Lactic AcidC) Carbon Dioxide and ATPD) Oxygen and carbon dioxide

AnswerC) Carbon Dioxide and ATP

Question13Which organism is NOT likely to carry out

cellular respiration?A) TreeB)MushroomC) Anaerobic RespirationD) Tiger

AnswerC) Anaerobic Respiration

Question14Which of the following is NOT a stage of cellular

respiration?A)FermentationB) Electron Transport C)GlycolysisD)Krebs Cycle

AnswerA) Fermentation

Question15What are the final products of cellular

respiration?

AnswerCarbon Dioxide (CO2), Water(H2O), ATP

Question16What begin the process of Fermenation?

AnswerPyruvic Acid and NADH

Question17How is CO2 Gotten rid of from your body?

AnswerExhaled

Question18Where does Glycolysis take place at?

AnswerCytoplasm (Cytosol)
