It is important to note that each type of trailer is not similar to the other types and that the dimension and weight capacity of each is based on the corresponding trucking specifications of a particular semi-tractor and trailer used.
Glucose is a six-memebered ring molecule found in the blood and is usually a result of the breakdown of carbohydrates into sugars. It enters cells through specific transporter proteins that move it from outside the cell into the cell's cytosol. All of the glycolytic enzymes are found in the cytosol.
In eukaryotic cells, the initial stages of glucose degradation occur in the cytosol, where two ATP molecules per glucose molecule are generated. The terminal stages, including those involving phosphorylation coupled to final oxidation by oxygen, are carried out by enzymes in the mitochondrial matrix and cristae (Chapter 16).
