<u>Answer: </u>
Four stages involved in cellular respiration does not function independently. Instead, they Dependent on each other.
<u>Explanation:</u>
Four stages in cellular respiration involves Glycolysis, link reaction, Kerbs cycle, electron transport chain.
Glycolysis is the initial stage in cellular respiration. In this stage, the glucose present in the cytoplasm is broken down into 2 molecules of Pyruvate.
The second stage is the link reaction or the bridge reaction. In this stage, the pyruvate produced in the first stage is pumped actively into the mitochondria. Now the pyruvate is converted into acetyl group by removing one molecule of and two molecules of
. This acetyl group combines with CoA Enzyme to produce acetyl CoA.
In the Kerb’s Cycle, the Acetyl CoA combines with oxaloacetate to form a 6 carbon atom compound.
Now in the electron transport chain stage, the energy released by the electrons are used to pump the hydrogen that was removed in the previous stages.
Thus the by-product of one stage is used as the source in another stage. Hence the cellular respiration process is not independent.
