How is metabolism regulated?

 Fast mechanisms, for immediate changes
  -Substrate concentration
  -Allosteric regulation (feedback, feed forward)
  (the regulation of an enzyme by binding an effector
  molecule at a site other than the enzyme’s active site).
  -Phosphorylation-dephosphorylation
  -Signals emanating from hormone action

Slow mechanisms, for long-term changes

 Genetic regulation
 Response to diet and other environmental variables
