The Cori Cycle, Glucose --> 2 Lactate + 2ATP (Muscle)

Multiple Choice

The Cori Cycle, glucose --> 2 lactate + 2ATP (Muscle) and 2 lactate + 6 ATP --> glucose (Liver) , is important because

A) there is a net destruction of ATP, restoring the energy balance between liver and muscle.
B) it results in the net generation of glucose in the liver and ATP in the muscles without the build up of high lactate levels.
C) it enables muscle mass to be used for energy in conditions of extreme starvation.
D) it serves to prevent lactate levels from dropping too low in the blood, which would impair brain function.
E) it enables glucose 6-phosphate to be transported across the liver cell plasma membrane.
