E) coenzyme derived from a vitamin.
(The answer is D. Why isn't it C?)
Thanks to anyone that can help out!
1. Heat given off in a reaction is enthalpy. Concentration is one of three factors (along with temperature of a system and partial pressure) that affect enthalpy of reaction. The concentration of 10000 ATP in a test tube will much higher than that same 10000 in the entire human body.
2. Water is not released in hydrolysis. It is used to break apart a bond. The -OH will bind to one product, and the -H to another.
3. G only depends on the Gproduct and Greactant. Whether there is one intermediate reaction or one thousand, whether you add exactly the required energy of activation or a hundred times more, whether it's catalyzed or not will NOT affect G. It will however affect the time required for the reaction to reach equilibrium.
4. These are all definitions. Allosteric means a site that isn't the active site.
