Question
Chapter 10, Problem 18CQ
Summary Introduction
To calculate: The time taken by 100 molecules of Valinomycin to transport enough K+ ions to change the concentration inside an erythrocyte of the given volume.
Concept introduction: Valinomycin is the characterized ionophore that specially binds to the K+ ion. It is a cyclic ionophore that contains ester linkage as well as peptide bonds, and D-amino acids and L-amino acids. Valinomycin is the channel-forming ionophore that forms transmembrane channels or pores through which the selected ions can pass through.

Biochemistry Question. Please help. Thank you.
You are studying pyruvate utilization in mammals for ATP production under
aerobic conditions and have synthesized pyruvate with Carbon #1 labelled with radioactive C14.
After only one complete cycle of the TCA cycle, which of the TCA cycle intermediates would be
labeled with C14? Explain your answer.
Interestingly, you find C14 being excreted in the urine. How does it get there?
