The Krebs Cycle, also called the citric acid cycle, is the second major step in oxidative phosphorylation. After glycolysis breaks glucose into smaller 3-carbon molecules, the Krebs cycle transfers the energy from these molecules to electron carriers, which will be used in the electron transport chain to … See more Most organisms use glucose as a major fuel source, but must break down this glucose and store the energy in ATP and other molecules. The Krebs cycle is contained within mitochondria. Within the mitochondrial matrix, … See more The first step of utilizing glucose, glycolysis, produces a few ATP as well as the molecules which will be processed with the Krebs cycle. During glycolysis, a single glucose molecule is split into two smaller, three-carbon … See more The Krebs cycle has 9 main reactions, which happen quickly in succession.
