Metabolic pathways are often regulated through feedback inhibition. This means:
The substrate of a pathway stimulates the first enzyme.
Enzymes are constantly synthesized regardless of product concentration.
The end product of a pathway inhibits an earlier enzyme in the pathway.
Enzymes are degraded rapidly after catalyzing a reaction.
