metabolic pathway
A geo (earth) bio (life) chemical (molecules/elements) pathway is a fancy way of saying nutrient cycle. Nutrients are a chemical which travels a cyclic pathbetween the earth and livingthings.
When an enzyme in a pathway is inhibited by the product of the reaction sequence, feedback inhibition occurs. The product molecule "feeds back" to stop the reaction sequence when the product is abundant.
