Front 5

The Krebs cycle occurs inthe mitochondria. There are nine biochemical reactions involved in the Krebs ccle and they are highly ordered. Select the correct order from the following choices. Note these are abbreviated and do not show NAD, ADP, ATP, FAD, or water.

Back 5

Acetyl-Coa joins the Krebs cycle and unites with oxaloacetate forming citrate which forms Isocitrate which forms alpha-ketoglutarate which forms fumarate which forms malate which foms oxaloacetate.
