Why is the krebs cycle called a cycle? the process begins in the matrix of the mitochondria, continues through the intermembrane space, and returns to the matrix. the final product of the process serves as an initial reactant in the process. the process consumes atp and nadh and then produces both. the acetyl coa used in the first step is immediately returned to the process of acetyl coa formation. the process begins in the cytoplasm, continues through the mitochondria, and returns to the cytoplasm?

The Kreb's cycle is also known as citric acid cycle or tricarboxylic acid cycle is the process which involves a series of reaction which is required to breakdown food into form of energy that a cell can use. The cycle starts in the mitrochondria of the cell where glycolysis takes place utilizing two molecules of pyruvic acid to produce energy molecules in the form of ATP. The end products of Kreb's cycle includes 2 ATP, 10 NADH, 2 FADH₂ and oxaloacetic acid molecules per 2 molecules of pyruvic acid. NADH and FADH₂ are accepted by the electron transport chain. The final product which is left after kreb's cycle is oxaloacetic acid. The Kreb's cycle is called as a cycle because oxaloacetic acid is the molecule required to accept an acetyl-CoA molecule and start another turn of the cycle.
