Track matter and energy through coupled pathways.
Metabolism is best understood as a regulated network of fluxes whose behavior depends on energy state, substrate availability and cellular context.
Catabolic pathways
Trace how carbohydrates, fats and amino acids are broken down to release usable energy and intermediates.
Anabolic pathways
Follow biosynthetic routes that build macromolecules while consuming energy and reducing power.
Pathway regulation
Study allosteric control, covalent modification and hormone-sensitive regulation as mechanisms that redirect flux.
Whole-body integration
Connect liver, muscle, adipose and other tissues across fed, fasting, exercise and stress states.
Keep the boundaries visible.
metabolic pathway ≠ linear pipeline
energy content ≠ ATP yield
blood metabolite level ≠ cellular flux
Questions that organize the Side.
Why can a pathway's metabolite concentrations remain stable while flux changes substantially?
How do tissues divide metabolic labor across different physiological states?
Which steps control pathway flux rather than merely participate in it?
What should carry weight here?
Use isotope tracing, enzyme kinetics, metabolomics and controlled physiological interventions; concentration data alone should not be treated as direct measurements of flux.
