In order to answer this question, let's talk about metabolism.
00:03
It says ultimately the high -energy electrons and cellular respiration come from.
00:08
And those electrons that at the end and in the electron transport chain, remember that the molecules that carry those electrons are nad and fad, okay, in their reduced form that are nadh and fadh too.
00:25
But those electrons ultimately, practically, come from glucose.
00:33
So those electrons that ultimately end here in the electron transport chain come from glucose.
00:39
Then it says those high energy electrons are stripped away and eventually are accepted by a molecule of and remember that those molecules will reduce form of an ad and fad that are an adhd and fadh and fdh2.
00:54
They are the electron donors and they are going to donate electrons to the electron transport chain in the final electron acceptor in the electron transport chain is going to be oxygen.
01:04
Okay, so oxygen is going to be the final electron receptor.
01:08
So this is the answer for blank number two.
01:10
Then it says, which then produces a molecule of and when oxygen accepts those electrons it is going to produce water.
01:21
Okay, so you have here water...
