You won't get to ride a motorcycle at the USA events, but they are terrific inspirational events (and I have a t-shirt from attending the Harley event in the USA that gets a LOT of attention whenever I wear it).
Also during the Krebs cycle, the two carbon atoms of acetyl-CoA are released, and each forms a carbon dioxide molecule. Thus, for each acetyl-CoA entering the cycle, two carbon dioxide molecules are formed. Two acetyl-CoA molecules enter the cycle, and each has two carbon atoms, so four carbon dioxide molecules will form. Add these four molecules to the two carbon dioxide molecules formed in the conversion of pyruvic acid to acetyl-CoA, and it adds up to six carbon dioxide molecules.
During each Krebs cycle, eight reactions should occur. As the reactions happen, the energy currency of the cell, adenosine triphosphate, known as ATP, is made. Continue Reading. Electrons are also given off during the Krebs cycle, which fuel the process of oxidative phosphorylation. Oxidative phosphorylation is a major source of ATP and energy. The first reaction in the cycle is the addition of an acetyl group to oxaloacetate by citrate synthase.
