Metabolism Cycle, Day and Night

Metabolism cycle may suggest some more ideas.

Metabolism cycle
Wake - catabolic activity
Sleep - anabolic activity.

Then I asked if there was some reason catabolic activity evolved in
the day or sunlight hours
And if there was some reason anabolic activity evolved in the night or
non sunlight hours.

Day - catabolic activity (wake)
Night - anabolic activity (sleep)

Day would have UV/sunlight and perhaps that would help promote
catabolic activity
Night would be free of UV and perhaps that would help protect the
anabolic build up.

That may give us early clues to how life evolved.
Day/ sunlight - catabolic chemistry thrived,
Night/ no sunlight - anabolic chemistry thrived
