Detailed explanation-1: -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 produce ATP.
Detailed explanation-2: -The main function of the Krebs cycle is to produce energy, stored and transported as ATP or GTP. The cycle is also central to other biosynthetic reactions where the intermediates produced are required to make other molecules, such as amino acids, nucleotide bases and cholesterol.
Detailed explanation-3: -The Krebs Cycle removes energy from citric acid in small steps, storing it in diverse energy carrier molecules: ATP, NADH and FADH2.
Detailed explanation-4: -Electron carriers such as NADH produced during glycolysis and the Krebs cycle pass their electrons to the electron transport chain, which results in synthesis of a lot of ATP.
