Aerobic Respiration And Aerobic Respiration

Since the beginning of the world there has always been one question in common between people around the planet. The question is: 'how did we come to existence?'. However, the answer is not always the same because everyone has different believes, but according to science eukaryotes came to existence because we evolved from prokaryotic cells. At the beginning of time, the only inhabitants of earth were microbes. Aerobic cellular respiration and oxygenic photosynthesis both play a big role in our evolution. Cellular respiration is a process that mostly takes place in the mitochondria where cells break down food and turn in it into adenosine triphosphate(ATP), or in more simpler terms, energy for the cell. Although cellular respiration can do either anaerobic or aerobic cellular respiration processes, it is usually used to describe aerobic cellular respiration because it actually was created as a synonym for aerobic respiration. Aerobic cellular respiration is the process where oxygen is used to make energy molecules. Aerobic respiration creates a lot more ATP molecules than in anaerobic respiration because anaerobic does not use oxygen as a reactant. Aerobic cellular respiration goes through three steps, and they are: glycolysis, citric acid cycle (Krebs cycle), and oxidative phosphorylation. Glycolysis means separating sugars, and in that process every glucose is turned into two pyruvate molecules. It then enters the mitochondria if it is a eukaryotic cell and the pyruvate
