Yay, ATP gives 30.6 kj mol-1 with every phosphate lost and requires 30.6 kj mol-1 with every phosphate gained in reformation. Hoorah for slightly mind numbing biological processes :)

Why do we still buy batteries?

Adenosine TriPhosphate is not a new discovery, though...

I learned about ATP in Natural Science class 20 years ago...

Let's just wait and see if this passes muster of peer review and publication first.


It's already been published, in the journal Chemical Communications.

Summary of summary: they think they've found a chemical that releases enough energy when broken down be able to make the components of 'primordial soup' - all the things required for life to begin.

(N.B, I know breaking bonds requires energy and it is the formation of new bonds that releases it - someone is bound to be a pedant and comment on that, I was just simplifying)

Finally a degree in biochemistry comes in handy!

Summary: Basically for anything to be made in a cell (proteins, amino acids, complexes etc), energy is required. Enzymes are 'machines' in our bodies that perform other functions like making other proteins. These machines are run by ATP (the equivalent of batteries). These batteries are 'charged' from the energy released when food is broken down.

The point they are trying to make here is that this ATP can be used to 'fuel' various chemical reactions within a cell but you need something with more energy to 'charge'/ make that ATP to begin with.

Much like saying the 'mains' can charge a car battery, the car battery can charge an AA battery and an AA battery can charge a watch battery. Here, the ATP is the AA battery and the pyrophosphite is the 'mains'.

An intermediate (the car battery) that you're all aware of is creatine which body builders use - this can be used to more efficiently 'make' ATP- ne

so hoe exactly did time start? cause sometin had to put time in motion and for that to have happend time must have already existed, every action has an equal and opposite reaction. :P

What is this "energy" they speak of?

- I've often wondered the very same thing

It's funny how all the comments after the article at first read like people trolling pretending to be christians, but they really believe that stuff.

Sorry for turning this into a religious debate, like all other things on iab.

we do know some things about it...it must have mass, or some effect like gravity, and it appears to bubble around each galaxy like a halo holding it in a perfectly synchronized spin from inside out...it doesn't work like it should. The outside arm (where we are) should be moving around the center of the galaxy slower than the inside--but that isn't true and they think dark matter is to blame. But whatevs.

'citing as-yet-unpublished evidence.'

I'd really enjoy if it we knew more about dark matter.

Not really "new".

Very interesting concept. I'm not certain how far they will get with it, but it is an interesting direction.
