When I look at the process of Cellular Respiration, it reminds
me of cleaning. When you are doing dishes for instance, you use a couple drops of liquid soap and you get all these bubbles
that will help clean the dishes. This is similar to Cellular Respiration because you put in or invest a small amount of energy
into each part of Cellular Respiration and you get all this energy out in return, most coming at the end through the ETC. The
end result of Cellular Respiration is 38/36 ATP and you only use 2 ATP to power Glycolysis and in the end you have 38 ATP.
Thats a pretty good exchange!
