Put the steps of Cellular Respiration in order.

Reorder answers
1.The electron transport chain, the NADH and FADH2 give up electrons, energy is released and captured as it moves from a high concentration to a low concentration. Energy is used to produce about 32-34 ATP.

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

3.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.

4.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.

The correct order of the steps of Cellular Respiration is as follows:

  1. 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. (Step 3)

  2. Two molecules of pyruvate move into the mitochondria where they are converted into Acetyl CoA. More NADH is produced and CO2 is released. (Step 2)

  3. 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. (Step 4)

  4. The electron transport chain, the NADH and FADH2 give up electrons, energy is released and captured as it moves from a high concentration to a low concentration. Energy is used to produce about 32-34 ATP. (Step 1)
