Relating to bioenergetics:
a. The equilibrium constant for a particular reaction is 6.8 x 10-5 which makes this reaction exergonic. True or False?b. All processes that occur in the universe are spontaneous and have low enough activation energies that molecules can often overcome the energy barrier. True or False?c. ATP has a highly negative free energy change in part because the negative charges on the oxygens repel each other in ATP but less so in ADP. True or False?
