Answer:
In a global sense, Cellular respiration takes place with the following process: Glycolysis, Pyruvate oxidation, Citric acid cycle (Kreb's cycle) and finally the oxidative phosphorylation. This corresponds to 12, 13, 11, 14, and 15.
Explanation:
In a global sense, Cellular respiration takes place with the following process: Glycolysis, Pyruvate oxidation, Citric acid cycle (Kreb's cycle) and finally the oxidative phosphorylation. Now, we will organize the presented steps in order to achieve Cellular respiration as follows:
First step: 12. 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.
Second step: 13. Two molecules of pyruvate move into the mitochondria where they are converted into Acetyl CoA. More NADH is produced and CO2 is released.
Third step: 1 1. 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.
Fourth step: 14. 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 a low concentration.
Finally, 15. Energy is used to produce about 34 ATP. Oxygen is the terminal electron acceptor that combines with oxygen to produce water
We can conclude that Cellular respiration takes place with the following process: Glycolysis, Pyruvate oxidation, Citric acid cycle (Kreb's cycle) and finally the oxidative phosphorylation. This corresponds to 12, 13, 11, 14, and 15.
