heme synthesis
The mitochondrion is an organelle in eukaryotic cells that performs various functions, including energy production, metabolism, and cellular signaling. One important pathway that occurs in the mitochondrion is the citric acid cycle or Krebs cycle, which involves the oxidation of acetyl-CoA to produce ATP and other key metabolites.
The synthesis that begins and ends in the mitochondrian matrix is the process of citrate synthesis. This process involves the joining of acetyl-CoA and oxaloacetate to form citrate. This reaction is catalyzed by the enzyme citrate synthase and occurs in the mitochondrial matrix.
The citrate produced in this reaction can be used for several functions in the cell. It can serve as a source of energy and is a substrate for the citric acid cycle. Citrate can also be used to synthesize fatty acids, cholesterol, and amino acids.
Overall, the synthesis of citrate that occurs in the mitochondrial matrix plays a critical role in the production of energy and the metabolism of various cellular processes.
