Richard: This field is going to represent the cytoplasm. We are representing glucose. So we start with one glucose, a 6-carbon-molecule and we split it in half to create two pyruvates The pyruvate sugars are also called pyruvic acid.
Max: When glucose is split apart into two pyruvates, we are left with two H2 molecules. Two NAD coenzymes are going to take some of those high-energy hydrogens and attach them to oxygen molecules to form water. When this occurs we have net gain of 2
Lea: 2 acetyl sugars are going to enter the cycle and they are going to be broken apart to form a carbon-dioxide molecule. At the end of the Krebs cycle, there will be no sugar. Four carbon dioxide molecules will form in this cycle. During this process, energy is released to form two ATP’s now having 4 ATP’s. This is known as phosphorylation. Not only are additional ATP’s formed, but lots of high energy hydrogens are left off from the broken acetyl sugars when they turned into CO2.
