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.
A G3P molecule contains three fixed carbon atoms, so it takes two G3Ps to build a six-carbon glucose molecule. It would take six turns of the cycle, or 6 6 6 6 C O 2 \text {CO}_2 CO 2 C, O, start subscript, 2, end subscript, 1 8 18 1 8 18 ATP, and 1 2 12 1 2 12 NADPH, to produce one molecule of glucose.
