I have this AP Bio 12 test coming up in a week. 1 question is something like this.
“How is ATP formed?”
And ATP is formed either by Chemiosis or Substrate-level phosphoratation.
I know what chemiosis does but how does substrate-level phosphoratation produce ATP?

phosphorylation is probably the term you should google for.

ATP is Adenosin TriPhosphate
so it could be formed by Nitrogen base (adenosin) and 3 phosphates
it could be said that it from AMP then + Pi become ADP, ADP + Pi become ATP.
hei… try molecular biology..
then try also DNA replication.
hei… also try something similar GTP, CTP..
hope this help

But doing a phosporylation is also the same…just do it by using proton pump..

Hey in chemiosmosis H+ ion gradient drives ATP synthesis. When H+ enter across membrane in direction of lower concentration-actually it crosses through ATP synthase in memebrane , ATP synthase gets energy for making ATP from ADP and Pi.
Substrate level production of ATP is a process in which ATP is produced by enzyme that transfers directly a phosphate group from substrate to ADP.Like in glycolysis from 1,3-biphosphoglycerate to 3-phosphoglycerate.

That’s what I mean proton pump… 😀
