What is feedback regulation of a metabolic pathway?

when an enzyme that is active early in a metabolic pathway is inhibited by a product of the pathway.

Metabolic pathway is the sum total of all the biochemical reactions in our body. It regulation or control is done by our genetic system through both hormonal and nervous control.

enzymes situated at key steps in metabolic pathways are modulated by allosteric effectors these effectors are usually produced elsewhere in the pathway effectors may be feed-forward activators or feedback inhibitors kinetics are sigmoid ("S-shaped")

Enzymes are catalysts in metabolic pathways.

Metabolic regulation is when genes tell their cells to produce enzymes and regulate their quantity. It controls the activity of metabolic pathways.

An enzyme near the beginning of a metabolic pathway is allosterically inhibited by the end product of the pathway. So the feedback inhibition realizes that once we get to a certin level of something made in the cell, it will become an allosteric enzyme and block production so nothing is overproduced in the cell.

A metabolic pathway that involvs both anabolism and catabolism.

Infact there are the significance of excretion.Firstly is the removal of unwanted by-products of metabolic pathway, removal of toxic wastes, and also regulation of ionic concentration, water content of the body fluids and lastly regulation of pH.

an accumulation of effectors slows the pathway.

If an enzyme is defective in a metabolic pathway, the pathway will come to a halt and no product will be produced. Imagine a person walking to the store and not able to cross the street (flooded?).

The metabolic pathway will predominate after eating a balanced meal is oxidative glycolysis. The citric acid cycle is a continuous circle of 8 metabolic reactions.

CORRECT ANSWER: photosynthesis
