Put the steps of Cellular Respiration in order.

1. Two molecules of pyruvate move into the mitochondria where they are converted into Acetyl CoA. More NADH is produced and CO2 is released.

2. Glycolysis takes place in the cytoplasm and breaks down glucose to form two molecules of pyruvate. 2 ATP are produced and NADH is saved for later.

3. In the Citric Acid/Kreb's Cycle the carbons that are left from the initial glucose are oxidized releasing more CO2. NADH and FADH2 and 2 ATP molecules are produced.

4. Energy is used to produce about 34 ATP. Oxygen is the terminal electron acceptor that combines with oxygen to produce water.

5. In the electron transport chain, the NADH and FADH2 give up electrons, energy is released and captured as it moves from a high concentration to
low concentration.
