Thermodynamics : ATPFromGlucose (8 Variations)
When glucose is oxidized in the human body it releases a lot of Gibbs free energy. Rather than waste this free energy, the body stores much of it in the form of ATP. The following reaction shows this process of storing some of the energy from glucose in ATP. This is an example of coupled reactions in a biological system.
The label on a can of Coke says that it contains 39 g of sugar. Assume that all of the sugar is glucose (even though it isn't), and calculate how many moles of ATP can be produced theoretically by the oxidation of 39.0 g of glucose.

Acids_and_Bases : ProtonTransferRxn (20 Variations)
Write an equation to describe the proton transfer that occurs when the following acid is added to water: HSO4-
Enter the products in the space below using the following as an example:
What ions are present in an aqueous calcium nitrate solution?
Ca(NO3)2(aq)  Ca2+(aq) + 2NO3-(aq)
In this case, the answer would be: Ca2+(aq) + 2NO3-(aq)
You should enter: Ca^(2+) + 2NO3^(-)
In other words, use the ^ to indicate superscripts; put charges in parentheses; and leave a space on either side of the + sign. Your answer must be an exact match for the computer to grade it correctly, so be careful.
