The conversion of pyruvate to acetyl-CoA in the mitochondrial matrix
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.
Test your knowledge of cellular respiration with questions about glycolysis, TCA cycle, and energy production from different macronutrients. Explore the key points of each process and the location of these metabolic pathways within the cell.
