Multiple Choice

The Krebs cycle occurs in the mitochondria.There are nine biochemical reactions involved in the Krebs cycle, and they are highly ordered.Select the correct order.(Note: These are abbreviated and do not show NAD, ADP, ATP, or FAD.)

A) acetyl-CoA joins the Kreb cycle and unites with oxaloacetate $\rightarrow$ forming citrate $\rightarrow$ which forms beta-ketoglutarate $\rightarrow$ which forms succinyl-CoA $\rightarrow$ which forms succinate $\rightarrow$ which forms fumarate $\rightarrow$ which forms malate $\rightarrow$ which forms oxaloacetate
B) acetyl-CoA joins the Kreb cycle and unites with oxaloacetate $\rightarrow$ forming citrate $\rightarrow$ which forms alpha-ketoglutarate $\rightarrow$ which forms succinyl-CoA $\rightarrow$ which forms succinate $\rightarrow$ which forms malate $\rightarrow$ which forms fumarate $\rightarrow$ which forms oxaloacetate
C) acetyl-CoA joins the Kreb cycle and unites with oxaloacetate $\rightarrow$ which forms alpha-ketoglutarate $\rightarrow$ forming citrate $\rightarrow$ which forms succinyl-CoA $\rightarrow$ which forms succinate $\rightarrow$ which forms fumarate $\rightarrow$ which forms malate $\rightarrow$ which forms oxaloacetate
D) acetyl-CoA joins the Kreb cycle and unites with oxaloacetate $\rightarrow$ forming citrate $\rightarrow$ which forms alpha-ketoglutarate $\rightarrow$ which forms succinyl-CoA $\rightarrow$ which forms succinate $\rightarrow$ which forms fumarate $\rightarrow$ which forms malate $\rightarrow$ which forms oxaloacetate
