The reason for the GTPase activity of G proteins to be crucial for the functioning of a cell needs to be explained. A theory for G proteins to be not evolved in the hydrolysis of GTP as a catalyst needs to be proposed. Concept introduction: GTPase activities are performed by the GTPases which are the families of hydrolase enzymes. G proteins are the kind of proteins which act as molecular switches inside the cells. They transmit signals from outside to interior.

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?
