Metabolic pathways

Question 1

What are threshold reactions?

Answer 1

Reactions in the crossovers between pathways which are highly regulated (contol entry to pathway)

Question 2

What are primary metabolic pathways?

Answer 2

Pathways present in all cells which produce important compounds needed (primary metabolites, eg. aas, nts, fats, sugs)
-largely constitutive
-house keeping functions

Question 3

What are secondary metabolic pathways?

Answer 3

Pathways present in differententiated cells with specialised functions which produce secondary metabolites (eg. antibioticsm plant products)
-inducible
