So one goes this way and the other one goes in reverse. So if the cell needs to break down glucose and produce ATP molecules, then what it does is basically shuts off gluconeogenesis. But if the cell has plenty amounts of ATP molecules and it doesn't actually want to break down the glucose, then gluconeogenesis is more likely to actually take place. In fact, we see that glycolysis and gluconeogenesis do not actually take place at the same exact moment in time. So when one process is activated, the other process is usually inhibited and vice versa. So now we know the general idea of what glucose metabolism actually is.
