The enzymes of the krebs cycle are located in the

The enzymes of the Krebs cycle are located in the matrix of the mitochondria.

Citric acid cycle also called tricarboxylic acid (TCA) cycle and Krebs cycle is a central process in cellular respiration. Citric acid cycle connects carbohydrate, fat, and protein metabolism so the products and intermediates from different metabolic pathways come to this cycle. Acetyl-CoA which is produced through the oxidation of pyruvate (pyruvate is a product of glycolysis) enters the cycle which then produces reduced electron carriers NADH, FAD2 and energy molecule ATP. These electron carriers will then pass their electrons into the electron transport chain and, through the process of oxidative phosphorylation, will produce more ATP.
