Glycolysis

Glycolysis:

• The splitting of the 6-carbon glucose molecule into two 3-carbon pyruvate molecules

Link reaction:

The 3-carbon pyruvate molecules enter into a series of reactions which lead to the formation of acetylcoemnzyme A, a 2-carbon molecule

Krebs cycle:

The introduction of acetylcoenzyme A into a cycle of oxidation-reduction reactions that yield some ATP and a large quantity of reduced NAD and FAD

Oxidative phosphorylation:

The use of electrons, associated with reduced NAD and FAD, released from the Krebs cycle to synthesise ATP with water produced as a by-product

Glycolysis:

• Takes place in the cytoplasm of cells
• Its reaction begins with the oxidation of glucose
• Energy is released and ATP is made

Phosphorylation of glucose:

• A glucose molecule is phosphorylated
• The reaction is endothermic…
