Explanation:
Detailed explanation-1: -The first step of cellular respiration involves the breakdown of glucose into a three-carbon compound called pyruvate.
Detailed explanation-2: -In organisms that perform cellular respiration, glycolysis is the first stage of this process. However, glycolysis doesn’t require oxygen, and many anaerobic organisms-organisms that do not use oxygen-also have this pathway.
