  • Good, hows your day so far?
  • Hi Christopher, how is your day going?
  • How? What is it?
  • Great. I learned about Cellular Respiration which is similar to Photosynthesis
  • What are they?
  • It occurs in everything! There are three steps.
  • The first is Glycolysis, which can be divided into two steps: the prep phase, and the payoff phase. In the prep phase, two ATPs are used to create an unstable molecule with a phosphate group on either end. The molecule is ready to be broken down in the payoff phase. In this phase, the molecule is broken down into 2 pyruvate molecules. From this, 4 ATPs are created. 2 NADPs, and H2O are also created. In the Prep phase before the Krebs Cycle, (for each pyruvate) a Coenzyme A joins with the pyruvate creating Acetyl-CoA, which is then passed on to the Krebs cycle, where it bonds with oxaloacetate to make a six-carbon atom.
  • And then what happens?
  • What happens in the electron transport chain?
  • From this, electrons and protons are donated to make NADH and CO2 is released. There is now a four-carbon molecule. Next, ATP, NADH, and FADH2 are made. The molecule is now oxaloacetate, and the second Pyruvate molecule (bonded with Coenzyme A) can begin the Krebs cycle by bonding with the oxaloacetate. The total creation for both is 4 NADH, 2 ATP, and 2 FADH2. The NADH and FADH are then sent to the electron transport chain.
  • Cool!
  • There, they donate their electrons to power pumps which pump H+ ions into the inner mitochondrial membrane to create a concentration gradient. The H+ ions then flow out of the ATP synthase, creating ATP. In this process, from one Glucose molecule, 38 ATPs are created.
