question 37

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
