Understanding Metabolic Pathways and Feedback Inhibition

Metabolic Pathways

Chains of reaction using product as substrates.

Enzyme

Catalysts specific to each reaction step.

Intermediate

A molecule formed during a metabolic pathway.

Endproduct

Final product of a metabolic pathway.

Equilibrium

State where reactants are fully consumed.

Non-equilibrium System

Cells continuously supply reactant, preventing equilibrium.

Steady State

Condition where reactions flow continuously.

Feedback Inhibition

Regulatory process controlling reaction rates.

Threonine

A key amino acid in meabolic pathways.

Threonine Deaminase

Enzyme catalyzing threonine conversion.

Isoleucine

Non-competitive inhibitor affecting threonine deaminase.

Substrate

Reactant molecule used by an enzyme.

Reaction Sequence

Order of reactions in a metabolic pathway.

Cell Type Specific Pathways

Unique pathways found in certain organisms.

Common Pathways

Pathways shared across all organisms.

Networked Pathways

Interconnected metabolic pathways within a cell

Catalyzing

The process of speeding up a reaction.

Reactant

Starting material for a metabolic reaction.

Product

Substance produced by a metabolic reaction.

Non-competitive Inhibitor

Slows reactions without stopping them
