When a city starts out with a major energy deficit, there are two changes that should be made: to be really, and I mean really efficient at recycling the critical resource, or to buy more energy. What about in biology? Cells are like cities, right? Out of Balance We already know from a previous post (“The Mystery of Energy Metabolism”) that the cell has an energy budget that is out of balance based solely on biosynthesis and use of ATP. It is in a predicament. It has an extreme shortfall in ATP in its balance sheet, needing six ATP just to make one. ATP is a high energy molecule. All that energy has to be loaded into the molecule during its synthesis by using up other ATP molecules. If chemical A is…
