Question

During exercise glucose consumption increases to 60 :mol min-1 100 g-1. Assume arterial [glucose] does not change. Blood flow increases to 0.60 ml min-1 g-1.G. What is the venous concentration of glucose during exercise?

Answer 1

Intracellular glucose concentration is low at rest but can under certain conditions such as intensive exercise and hypoxia increase to maximum values of 3-4 mmol/l of intracellular water which demonstrates that glucose uptake under certain conditions can be in excess of the utilization of glucose.
