8) each time a molecule of glucose is completely oxidized via aerobic respiration, how many oxygen (o2) molecules are required?
a) 1
b) 2
c) 6
d) 12
e) 38

C) 6

Explanation:

The balanced equation for aerobic cellular respiration is:

C₆H₁₂O₆ + 6 O₂ > 6 CO₂ + 6 H₂O + Energy (ATP)

For each glucose molecule that's oxidized, 6 oxygen molecules are used in order to produce ATP. Carbon dioxide and water are byproducts of aerobic respiration..
