Detailed explanation-1: -In eukaryotes, the Krebs cycle reactions take place in the mitochondrial matrix, a dense solution that surrounds the mitochondria crests: in addition to water, the matrix contains all the enzymes necessary for the biochemical reactions of the cycle, coenzymes, and phosphates.

Detailed explanation-2: -The mitochondrial matrix has the required enzymes and environment for the complex reactions of the Krebs cycle to take place. Further, the products of the Krebs cycle drive the electron transport chain and oxidative phosphorylation, both of which occur in the inner mitochondrial membrane.

Detailed explanation-3: -The Krebs cycle is a part of cellular respiration. The Krebs cycle comes after the link reaction and provides the hydrogen and electrons needed for the electron transport chain. It takes place inside the matrix of mitochondria.

Detailed explanation-4: -Location: This cycle occurs in the matrix of mitochondria ( cell organelle present in eukaryotic cells).

Detailed explanation-5: -The Krebs cycle takes place in the mitochondrial matrix. The products of glycolysis, which takes place in the cytosol, are brought to the mitochondria for the Krebs cycle and electron transport chain.
