Cells
need ATP for three different kinds of work. Transporting different molecules,
making various macromolecules, and muscle contractions. The purpose of cellular
respiration in animals is to take energy out of molecules of ATP for cellular
activities because most animals are not self sufficient in energy. This process
requires the use of oxygen. Most of the process of cellular respiration takes
place in the mitochondria, cell organelle (the power house of the cell). The
end results of cellular respiration are water, carbon dioxide, and many
adenosine triphosphate (ATP) molecules. The first part of cellular respiration
is Glycolosis. This is where Glucose is split into 3 carbon molecules. These
molecules will go through chemical reactions and will eventually become Acetyl
CoA. Acetyl CoA can also be called pruvatic acid. It will still be referred to
as Acetyl CoA in this passage. Acetyl CoA will then diffuse into the
mitochondria from where Glycolosis took place in the cytoplasm. The second part
of cellular respiration, The Citric Acid Cycle also known as the Kreb’s Cycle,
is where the Acetyl CoA is broken down further into hydrogen positive ions,
energized electrons, carbon dioxide, and ATP. The carbon dioxide is released
into the air. The third part of the cellular respiration process will carry the
hydrogen positive ions and the energized electrons to their new destination,
the electron transportation system, using molecules called FAD and NAD. These
are called hydrogen / electron carriers. During the electron transport system,
the hydrogen atoms dropped off by the FAD and NAD hydrogen / electron carriers
are combined with oxygen to produce H₂0. The excited electrons fall down to
their original levels creating energy. From one glucose molecule, cellular respiration
can create 38 ATP molecules. These molecules then get used for the three
different kinds of work stated above.
