The Krebs Cycle Occurs in the Mitochondria $\rightarrow$ Forming Citrate $\rightarrow$ Which Forms Beta-Ketoglutarate

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 from the following choices. (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 fumarate $\rightarrow$ which forms malate $\rightarrow$ which forms oxaloacetate
C) 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
D) 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
