New cards
15
aerobic respiration
However, ________ is the most effective catabolic route, in which oxygen is used as a reactant alongside the organic fuel (aerobic is derived from the Greek aer, air, and bios, life)
New cards
16
cellular respiration
The term ________ refers to Including both aerobic and anaerobic processes. However, it originated as a synonym for aerobic respiration because of the relationship of that process to organismal respiration, in which an animal breathes in oxygen.
New cards
17
