aka TCA -- Tricarboxylic Acid Cycle
aka CAC -- Citric Acid Cycle
ADP is phosphorylated to ATP. High-energy bond is formed.
(in this case a GDP -->GTP happens first, which immediately phosphorylates an ADP)
Water is added to a molecule.
Carbon dioxide is removed from a molecule.
NAD+ is reduced to NADH + H+ (aka NADH2 or NADre)
NAD has accepted a high-energy electron -- it will hold the energy until needed in another part of the cycle.
(Nicotinamide adenine dinucleotide)
FAD+ is reduced to FADH + H+ (aka FADH2 or FADre)
similar in function to NAD
(Flavin adenine dinucleotide)
