What does seem evident though is that structurally, long-term memories are stored in a different place than short-term memories and almost certainly in a very different way. We know this through the observation of patients with memory deficits (see the page on the Hippocampus).
And so, using these kind of estimations, they calculated essentially the upper range of ATP so, these calculations were ultimately used to calculate kind of this number of 38 ATP produced in cellular respiration, kind of the upper limit of ATP produced.
In aerobic respiration in the mitochondria, there are 2 moles of ATP produced in the citric acid cycle (Krebs cycle) by substrate-level phosphorylation, and between 32 and 34 moles of ATP produced by oxidative phosphorylation through the electron transport chain and chemiosmosis.
