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: -Explanation: The Krebs cycle takes place within the mitochondrial matrix of mitochondria. Glycolysis occurs in the cell’s cytosol.
Detailed explanation-3: -The citric acid cycle, also known as the Kreb’s cycle, occurs within the mitochondria of eukaryotic cells. In prokaryotic cells, it occurs in the cytosol.
Detailed explanation-4: -The Krebs cycle happens only within the mitochondrial matrix. Pyruvate is formed in the cytosol of the cell, then imported into the mitochondria. Here, it is converted to acetyl CoA and imported into the mitochondrial matrix.
