C4 has one step in the pathway before the Calvin Cycle which reduces the amount of carbon that is lost in the overall process. Atmospheric CO 2 dropped from Eocene levels above 1000 ppm to well below 700 ppm about 32 million years ago, and the first C 4 plants appeared around this time . C4 is an efficient biochemical modification of the C3 Plants. MBL pathway resembles classical pathway as it proceeds through the action of C4 and C2 to produce activated proteins of the complement system. The C 4 pathway is in effect a turbocharger for the more conventional C 3 pathway. C4 plant lose 277 molecules of water to fix per molecules of co2 as compared to c3 use 833 molecules of water approximately at 30 c. They also avoid photorespiration process. This is the currently selected item. Oecologia 112, 285.) The C3 pathway requires 18 molecules of ATP for the synthesis of one molecule of glucose, whereas the C4 pathway requires 30 molecules of ATP. Components of the CP are C1q, C1r, C1s, C2 and C4. Activation of the classical pathway will typically result in lowering of both C3 and C4, and therefore disorders in which BOTH C3 and C4 are decreased include lupus nephritis and cryoglobulinemia.
