QUESTIONS WITH COMPLETE ANSWER
KEY

●● fermentation
Answer: is a partial degradation of sugars that occurs without O2


●● Aerobic respiration
Answer: consumes organic molecules and O2 and yields ATP


●● Cellular respiration
Answer: -includes both aerobic and anaerobic respiration but is often
used to refer to aerobic respiration
-Although carbohydrates, fats, and proteins are all consumed as fuel, it is
helpful to trace cellular respiration with the sugar glucose:
C6H12O6 + 6 O2 6 CO2 + 6 H2O + Energy (ATP + heat)
