Answer:
It needs oxygen in order to occur.
Step-by-step explanation:
Cellular respiration is this process in which oxygen and glucose are used to create ATP, carbon dioxide, and water; ATP, carbon dioxide, and water are all products of this process because they are what is created.
The reactions of cellular respiration can be grouped into three stages: glycolysis (stage 1), the Krebs cycle, also called the citric acid cycle (stage 2), and electron transport (stage 3)
The other three stages of cellular respiration—pyruvate oxidation, the citric acid cycle, and oxidative phosphorylation—require oxygen in order to occur.
