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: -Two carbons-from acetyl CoAstart text, C, o, A, end text-enter the citric acid cycle in each turn, and two carbon dioxide molecules are released.
Detailed explanation-3: -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-4: -The stages of cellular respiration are glycolysis, pyruvate oxidation, Kreb cycle and oxidative phosphorylation. The waste product of carbon dioxide is created in cellular respiration.
