1) The irreversible steps in glycolysis and gluconeogenesis are points for coordinated regulation of flux through these pathways. Which of the isozymes, hexokinase II or hexokinase IV, reaches halfVmax at lower substrate concentrations and how doesthis make sense physiologically? 2) a- What is reciprocal regulation? Describe how this mechanism works […]

Due to very high glomerular filtration rates, nearly the entire volume of the blood enters the renal tubules every 30 minutes.  Obviously, most of it […]
