by PHOSPHORYLATION... adding a phosphate to ADP ADP + P ------> ATP
a) substrate level phosphorylation... where a substrate molecule ( X-p )
donates its P to ADP making ATP
b) chemiosmosis –
[Oxidative Phosphorylation of Krebs cycle & ETC]... food substrates donate e- &
protons to acceptor molecules [NADH], i.e., oxidation.
NADH gives up electrons & protons
are pumped out of mitochondria (or the chloroplasts in photosynthesis);
protons diffuse back into mito thru an enzyme - ATPase, the ATPase enzyme makes ADP + P --> ATP
