If things happened out of order, the cell wouldn't work at all. There are a lot of different signal pathways that ensure timing is correct. You can take a look at even the most basic functionalities like DNA replication, or energy exchange. And the cell is not timed only in regards to itself, but based on the system it lives in, too - and that system is timed too, repeat x1000000.
Humans (and other living beings) can work with such low amount of waste heat and intake energy only thanks to atomically precise clocking.
