Detailed explanation-1: -After citric acid forms, it goes through a series of reactions that release energy. The energy is captured in molecules of NADH, ATP, and FADH2, another energy-carrying compound. Carbon dioxide is also released as a waste product of these reactions.
Detailed explanation-2: -Energy is released when the 6-carbon arrangement is oxidized, causing one carbon to be removed. The removed carbon molecule combines with oxygen to produce CO 2start subscript, 2, end subscript. Some of the energy, in the form of electrons, is captured in formation of high-energy compound, NADH.
Detailed explanation-3: -For one cycle, two molecules of carbon, three molecules of NADH, one molecule of FADH2 and one molecule of ATP or GTP are produced.
Detailed explanation-4: -Krebs cycle produces the following: Two molecules of carbon dioxide are given off. One molecule of ATP is formed. Three molecules of NADH are produced.
