Truck Ratings for RV Towing. Quite a few options exist for towing a recreational vehicle, but four truck brands dominate the U.S. market: Chevrolet, Dodge, Ford, and GMC.
The linear form of glucose shown above makes up less than 3% of the glucose molecules in a water solution. The rest is one of two cyclic forms of glucose formed when the hydroxyl group on carbon 5 (C5) bonds to the aldehyde carbon 1 (C1), as shown below.
The complete oxidation of glucose involves four phases. 1  1. Glycolysis, the splitting of glucose into two 3-carbon molecules. 2  2. The preparatory reaction, which divides each 3-carbon molecule into a 2-carbon molecule and CO2. 3  3. The citric acid or Krebs cycle, which produces CO2, NADH, FADH2, and ATP.
