How do cells get energy from ATP?

Specifically, I’m trying to understand how the cell manages to use the energy from splitting ATP. I understand your cells split off a phosphate which releases energy that your cells use to… well, do cell stuff. What I don’t understand is how the cell takes the energy from that and does something with it- eg building a new cell.

The Purge must have been really stinky

So I was doing some generic clip watching when I saw this scene and it got me thinking about something-

When a person dies, they void their bowels. The nervous system shuts down, muscles relax, and anything inside your bowels comes out. This usually happens pretty quickly after, especially if the body is disturbed. And there was a WHOLE lot of that going on during the purge. We don’t know exactly how many die, but considering that even AFTER the purge billions died from the scourge virus, it’s likely the purge itself killed over a billion people. And every single one of them crapped their pants after dying, not to count the general odor from rotting corpses and disembowelings.

This leads me to the conclusion that the purge, especially that spot where Kregg, Thula, and Conquest were standing near a HUGE pile of bodies, must have been mighty stinky. Like a Taco Bell bathroom when they bring back nacho fries, or your average New Orleans street.

Anyways, thanks for coming to my TED talk.

Edit: Upon further thought, Mark choking out Conquest also probably stank something fierce. When he got turned into a donut, the muscles that hold your dookie were obliterated. And when conquest died, Mark was sitting on his stomach. So they were both probably shitting their pants, and I kind of want to see an edit of that scene but with the appropriate audio of them laying out a chocolate present in their pants.

Could the matter/antimatter imbalance be a local phenomenon?

So I want to preface this by saying I am, by no means, a physics expert. I’m just someone who’s always had an interest for physics but never had the mathematical inclination to truly study it. I don’t claim to know better than the experts, I mostly ask this to understand how we know it’s NOT the case. That being said:

I know that, as far as we know, the universe at the big bang should have made equal parts matter and antimatter. They should have annihilated instantly and basically naught but energy and gamma ray photons would remain. Except for some reason, for every billion matter/antimatter pair generated an extra matter particle was made (idk if that’s the exact ratio). This extra particle in a billion pairs led to all the matter we see now, but we’re not really sure *why* this extra particle was made.

My question is this- we have no earthy idea how big the true universe is, assuming it’s not just infinite; could the answer be that the universe, as a whole, did create an even amount of matter and antimatter… but on very small localized levels, an imbalance was created? How do we KNOW for sure that this imbalance is something we can extrapolate to the entire universe and create an issue in physics? Could there be small pockets of the universe where more anti-matter was made, and so for an observer their entire universe would be antimatter?
