Are the caffeine in green tea and coffee different?

A. 1

I've seen green tea and coffee experiments before.
In fact, coffee has a sharpness at once and then drops sharply
I've seen green tea wake up very slowly.

This is because the caffeine in green tea and coffee is not different from each other, but catechin in green tea prevents caffeine absorption.

If you compare the same amount of green tea and coffee, coffee contains twice as much caffeine as green tea.
It's because caffeine is good for hot water.
Coffee is produced in 100 degrees of water
For green tea, use 70 to 80 degrees of water.

The amount of coffee that is actually absorbed is much higher.
The reason is because of the catechin in green tea, as mentioned above.

Therefore, it is much better to drink green tea more often than coffee for a steady awakening effect.
