A chemical process in which oxygen is used to make energy from carbohydrates (sugars). Also called aerobic metabolism, cell respiration, and oxidative metabolism.
Examples for aerobic respiration are all multicellular organisms like birds, animals, insects, humans etc.

Answer:
C is Snotase, because it works best in neutral environments (hence the pH of 7)
A is Flotase because it works best in acidic environments (low pH)
B is Zoomase because it works in acidic environments (low pH)
D is Floxase because it works in basic environments (pH above 7)
Note:
For pH, 7 is considered neutral.  Anything below that is acidic and anything above that is basic.
