river is both a troll and ignorant...something that's as obvious as dog's balls.

Your well behind in this discussion , we are are long past this .
Please Register or Log in to view the hidden image! I'm pretty sure no one here. familiar with your nonsensical claims and trolling, have changed their minds about you.
I'm pretty sure you can't speak for anyone , other than yourself .
Anymore stupid fucking claims river?
And the thousands say ?
Molecular oxygen. O2.
Atomic oxygen is extremely reactive. It will combine with other atoms at the drop of a hat. Any. Hat. Which is why you don't find it slouching about by itself.
It is actually quite toxic to life (part of a group called free radicals) because it essentially "burns" anything it comes into contact with (that's what oxidation is, after all).
Most algae is phytoplankton which generates oxygen. Occasionally when the "wrong" type of nutrients are present in the water (like phosphates and nitrates) that causes growth of types of algae that use oxygen - thus leading to oxygen depleted areas. Red tides are an example of this.
Have you ever had a soda? Carbonated water is just water with CO2 dissolved in it. Oxygen can be dissolved in water the same way.
Agreed ( about free radicals )
Now how does O2 get utilized without becoming a free radical ?
Are you asking how organisms use O2? Google the Krebs Cycle. For a short answer, C6H12O6 + 6O2 = 6CO2 + 6H2O + ATP. ATP is, of course, what powers the various reactions in your body that keep you alive.
Yes, you are.
No I'm asking how O2 is utilized without becoming a free radical .
C6H12O6 + 6O2 = 6CO2 + 6H2O + ATP. Sugar plus oxygen gives you CO2, water and energy. That's how it's utilized.
Does O2 become a free-radical ?
I give up. Does someone else want to deal with mr. strong-opinions-little-knowledge here for a while?
Two bans due to warnings from this thread.
One for flaming and the other for trolling.
A few things to note..
This thread is no longer on topic (and I do not know if this is a blessing or not at this point in time!.. I kid!).
Certain individuals seem intent on trolling and flaming each other.
One individual has decided to ignore all responses to his questions and keeps asking the same off topic question over and over again.
Another individual has followed individual 1 into this thread and others to flame and troll..
I've had enough of this ridiculous behaviour and have moderation hammer in hand if it continues and I will take zero pity on anyone.
So happy we all got to have this chat. So much so that I've made this mod note hot pink in the hope that it burns into your retinas.
In fact, there is a non-trivial aspect to this. There is a valid question here about what the mechanism is by which this reaction, which is essentially the same as combustion, can take place at ambient conditions in a cell, without generating the highly reactive and hence destructive radical intermediates one sees in a combustion reaction.
This point is glossed over in most standard biochemical explanations, which always seem to witter on in an unsatisfying way about "pathways" and "electron transport chains", without showing any actual mechanisms at the molecular level. (This is one reason why I avoided the biochemistry supplementary option at university and went for the hardcore QM option instead Please Register or Log in to view the hidden image!)
I've dug into this and it seems molecular oxygen is handled by cytochrome oxidase, which contains a heme structure involving Fe and also a structure involving Cu. Oxygen is apparently bound to Fe, rather as it is in haemoglobin in the blood, and reacts attached to this site in some way. But it looks as if the details of precisely how the O=O bond is split and the two resulting O atoms are handled is, or was until recently, still a topic of research. Here is an article from 1999 with more details: https://www.pnas.org/content/96/23/12971
