Study Notes

Amino Acid Transdeamination

The transdeamination of amino acids produces ammonia and an alpha-keto acid.

Cellular Location of Metabolic Pathways

Glycolysis takes place in the cytosol.
The TCA (Citric Acid) cycle occurs in the mitochondria.
The Electron Transport Chain (ETC) is located in the mitochondrial inner membrane.

Aerobic Glycolysis

Aerobic glycolysis occurs in certain tissues, such as muscle, brain, and macrophages.
This process is also known as the "Warburg effect".

Function of Aerobic Glycolysis

The function of aerobic glycolysis is to provide energy for the cell, even in the presence of oxygen.

The Link Reaction

The Link reaction (also known as the pyruvate dehydrogenase complex) connects glycolysis to the Citric Acid cycle.
It converts pyruvate into acetyl-CoA, which then enters the TCA cycle.
