Complete the paragraph describing the fate of glutamate, labeled at the Cγ position with 14C, once it has been introduced to the TCA cycle.

 

In the second round (A.) 50%,B.) 25%, C.)or NONE of the label is lost) , however, in each subsequent cycle (25%,50%, or NONE of the label is lost). This occurs becuase at the end of the second round the label is (A.)Equally dsitributed among all carbons B.) part of the carboxylate group C.) Positioned on the erminal Carbon)  of oxaloacetate and each cycle (A.) releases a carbon B.) Releases two carbons C.) adds a carbon)  from oxaloacetate.

b Complete the paragraph describing the fate of glutamate, labeled at the Cy position with 14c,
once it has been introduced to the TCA cycle.
In the second round
however, in each subsequent cycle
This occurs because at the end of the second round the label is
of oxaloacetate and each cycle
from oxaloactetate.

Step 1

Glycolysis is the process of converting glucose to acetyl-CoA. During aerobic conditions, the TCA acid cycle follows. Acetyl-CoA is metabolized to carbon dioxide in this cycle. Tricarboxylic acid (TCA) or citric acid cycles are other names for this cycle.
