    Study Notes

    PDH Complex Overview

    • The primary function of the PDH complex is to catalyze the conversion of pyruvate into Acetyl-CoA, which is then fed into the citric acid cycle.

    Structure and Components

    • The PDH complex is housed in the mitochondria, the cellular organelle responsible for energy production.

    Cofactor Requirements

    • The PDH complex requires thiamine pyrophosphate (TPP) as a cofactor to function properly.

    Composition

    • The PDH complex stands for Pyruvate Dehydrogenase Complex, a multi-enzyme complex composed of multiple components, including E1, E2, and E3.

    Functionality

    • As a key component of cellular respiration, the PDH complex plays a crucial role in energy production, facilitating the link between glycolysis and the citric acid cycle.
