Big Idea 2, #3, 18,27. ATP, Glycolysis, Krebs Cycle. ATP is adenosine triphosphate, and it contains a lot of energy in its phosphate bonds. This energy can be used to power many things, like swimming with the above Tetra Fish. Glycolysis is the breakdown of glucose that releases NADH and pyruvic acid to make ATP. These goldfish are an example of this because they are constantly breaking down the glucose in the food they eat to make ATP to power the chemical reactions necessary for survival. The Krebs Cycle utilizes the pyruvic acid and makes more FADH 2 and NADH to make ATP. These Tinfoil Barb Fish constantly perform this cycle in their bodies to make the ATP necessary for life's reactions.
