Glucose Term paper

While the free essays can give you inspiration for writing, they cannot be used 'as is' because they will not meet your assignment's requirements. If you are in a time crunch, then you need a custom written term paper on your subject (glucose)
Here you can hire an independent writer/researcher to custom write you an authentic essay to your specifications that will pass any plagiarism test (e.g. Turnitin). Waste no more time!

Extracting energy from glucose

Two different pathways are involved in the metabolism of glucose: one anaerobic

and one aerobic. The anaerobic process occurs in the cytoplasm and is only

moderately efficient. The aerobic cycle takes place in the mitochondria and is

results in the greatest release of energy. As the name implies, though, it

requires oxygen.

Anaerobic metabolism

Glucose in the bloodstream diffuses into the cytoplasm and is locked there by

phosphorylation. A glucose molecule is then rearranged slightly to fructose and

phosphorylated again to fructose diphosphate. These steps actually require

energy, in the form of two ATPs per glucose. The fructose is then cleaved to

yield two glyceraldehyde phosphates (GPs). In the next steps, energy is finally

released, in the form of two ATPs and two NADHs, as the GPs are oxidized to

phosphoglycerates. One of the key enzymes in this process is glyceraldehyde

phosphate dehydrogenase (GPDH), which transfers a hydrogen atom from the GP to

NAD to yield the energetic NADH. Due to its key position in the glycolytic

pathway, biochemical assays of GPDH are often used to estimate the glycolytic

capacity of a muscle cell. Finally, two more ATPs are produced as the

phosphoglycerates are oxidized to pyruvate.

Aerobic metabolism

Pyruvate is the starting molecule for oxidative phosphorylation via the Krebb's
