Kreb's cycle

-aerobic process

-occurs in inner membrane of the mitochondria

-The citric acid cycle, also called the Krebs cycle, is a series of chemical reactions similar to the Calvin cycle in that the molecule used in the first reaction is also one of the end prod­ ucts. Read Figure 9.10 to study the citric acid cycle.
For every turn of the cycle, one mol­ ecule of ATP and two molecules of car­ bon dioxide are produced. Two electron carriers are used, N A D + and FAD (flavin adenine dinucleotide). A total of three NADH, three H+ ions, and one FADH2 are formed. The elec­ tron carriers each pass two energized electrons along to the electron trans­ port chain
