Description

Nutrients are required for a chemical reactions (substrates or cofactors) whose rate is dependent on their presence

Signals regulate the reaction rate giving (how???) some information (which one ???) concerning the availability of nutrients (T3/T4 = oxygen, insulin = serum glucose etc.)

As a matter of fact the whole metabolism is always and only regulated by its own substrates either directly or through a signal
