The main purpose of Kreb's Cycle is to reduce the electron carriers: FADH2 and NADH. These electrons are then passed to the electron transport chain by these carriers to generate a concentration gradient of Hydrogen ions between the intermembrane space and matrix of the mitochondria. This drives ATP synthase where the actual majority of ATP is synthesized.
I believe it is.
good luck
1 one is correct.....he never think about linkage......later after chromosome mapping it was found that Mendel was lucky that they don't show much linkage !
