In this question, we want to know whether or not or how circadian rhythms are affected by cell metabolism.
00:12
So normally humans and all organisms partition their daily behavior into both activity and rest phases based on whether or not it's day or night.
00:23
These phases differ in their metabolic requirements.
00:27
We don't require as much energy to be used by ourselves when we're asleep compared to when we are awake.
00:33
The circadian clock evolved as a timekeeping system that aligns behavior patterns with the external environment.
00:46
So basically, inside of our brains, there is a circadian clock that is able to keep time for us, and it aligns our behavior patterns with the changing of night to day.
01:01
So this clock supports body functions by coordinating metabolic functions.
01:17
So the metabolism within our cells with the day and night cycle.
01:29
And each cell of the body is equipped with its own circadian oscillator that is controlled by the master clock.
01:36
So essentially, in the cells of the body, there is something that allows the cells to, basically, controlled by the master clock or the circadian rhythm that our body experiences...
