The pet carboxylates and the pyruvate carboxylates are both inactivated by ADP. And so we conclude that when ATP is plentiful in a cell, the gluconeogenic process gluconeogenesis predominates, while when ATP is scarce, glycolysis is the process that predominates. Now, one more thing I want to mention before we discuss how glucose affects these two processes in the next lecture is the following. Sometimes you'll hear that Latitude's principle basically dictates which one of these processes will actually take place. And that's not exactly right. We cannot use legit Lee's principle to explain why either this process takes place or the other process takes place.
