Question8
 Lactic Acid Fermentation occurs in:
Answer
 Muscle cells
Question9
 Glycolysis provides a cell with a net gain of:
Answer
 2 ATP
Question10
 How many ATP are produced at the end of cellular
respiration?
Answer
 36
Question11
 What does NADH do?
Answer
 Carries electrons from Glycolysis to the Kreb cycle. Then
NADH and FADH2 carry them to the Electron Transport
Chain.
Question12
 While investigating yeast respiration, a researcher detect
ethanol in the yeast culture. Which molecules does the
yeast culture also contain?
 A) Lactic Acid and ATP
 B)Oxygen and Lactic Acid
 C) Carbon Dioxide and ATP
 D) Oxygen and carbon dioxide
Answer
 C) Carbon Dioxide and ATP
Question13
 Which organism is NOT likely to carry out cellular
respiration?
 A) Tree
 B)Mushroom
 C) Anaerobic Respiration
 D) Tiger
Answer
 C) Anaerobic Respiration
Question14
 Which of the following is NOT a stage of cellular
respiration?
 A)Fermentation
 B) Electron Transport
 C)Glycolysis
 D)Krebs Cycle
Answer
 A) Fermentation
Question15
 What are the final products of cellular respiration?
Answer
 Carbon Dioxide (CO2), Water(H2O), ATP
Question16
 What begin the process of Fermenation?
Answer
 Pyruvic Acid and NADH
Question17
 How is CO2 Gotten rid of from your body?
Answer
 Exhaled
Question18
Where does Glycolysis take
place at?
Answer
