What is the advantage of using ATP as a common energy source?Another way of asking this question is, “Why does ATP provide anadvantage over using a bunch of different food molecules?” For example,instead of just having a Na+/K+-ATPase in a cell, why not have manydifferent ion pumps, each driven by a different food molecule, like aNa+/K+-glucosase (a pump that uses glucose), a Na+/K+-sucrase (a pumpthat uses sucrose), a Na+/K+-fatty acidase (a pump that uses fatty acids),and so on?

What is the advantage of using ATP as a common energy source?
Another way of asking this question is, “Why does ATP provide an
advantage over using a bunch of different food molecules?” For example,
instead of just having a Na+/K+-ATPase in a cell, why not have many
different ion pumps, each driven by a different food molecule, like a
Na+/K+-glucosase (a pump that uses glucose), a Na+/K+-sucrase (a pump
that uses sucrose), a Na+/K+-fatty acidase (a pump that uses fatty acids),
and so on?
