Final answer:
Alternate oxidation routes in cellular respiration have functions in generating ATP through oxidative phosphorylation and removing carbon dioxide and high-energy electrons during the citric acid cycle.
Step-by-step explanation:
Alternate oxidation routes play important functions in cellular respiration. One function is the generation of ATP through oxidative phosphorylation. This process occurs during the electron transport chain, where high-energy electrons from NADH and FADH2 are used to generate ATP. Another function is the removal of carbon dioxide and high-energy electrons during the citric acid cycle, which helps break down glucose and produce more ATP.
