If a molecule of glucose is labeled with 14C at position 1 proceeds through glycolysis, where will the radioactive label end up?
a) At the carboxyl carbon of all the pyruvate produced
b) At the carboxyl carbon of half of the pyruvate produced.
c) At the methyl carbon of half of the pyruvate produced.
d) At the methyl carbon of all the pyruvate produced.
e) At the carbonyl carbon of all the pyruvate produced.
f) At the carbonyl carbon of half of the pyruvate produced.
Homework Answers
Ans. At the methyl carbon of all the pyruvate produced.
If the C1 carbon of the glucose were labelled with 14C, the methyl carbon atoms in the pyruvate would be labelled after glycolysis.
