We study cellular respiration because it is one of the most important pathways in biology. In fact, nearly all
carbohydrates at some point in their catabolism are directed through cellular respiration. Why is it unnecessary to have multiple independent pathways to break down different molecules?
a. Using cellular respiration is theoretically the most efficient way to break down sugars and other molecules. b. Oxygen must be used in the breakdown of all molecules in order to yield ATP. c. Greater complexity would lead to an eventual failure of the biological system. d. Most biological cells only catabolize one or two different types of sugars and only need one main pathway. e. Energy-containing macromolecules can be converted to products that can enter at various points in the cellular respiration pathway.
