<<Built into your analysis is the assumption that the _cell_ is somehow
interested in recovering the old-energy because going up down
escalators is the long term mission of a cell.

A cell does "defy" entropy in the sense that it invests some
energy in searching for new-energy inaddition to producing the things
its needs.

Nah, not really. The processes of the cell decreases it's own entropy (increases it's "order") but at the expense of creating extra disorder (increasing entropy) in the whole area around its operations. Let's just say that after the cell has done its thing, its personal entropy/disorder has decreased by say 2 units.The entropy/disorder of the surrounding area has increased by, say 10 units. Had the cell not been there, the entropy/disorder of the area would not have increased as much. The net result of life is that the Universe will end up in heat death earlier...
