Imagine a muscle cell that undergoes a high degree of contraction. What scenario is likely to describe the activity of glycolysis and the pentose phosphate pathway in these cells? A) It has a low activity of glycolysis and a low activity of the pentose phosphate pathway.
B) It has a high activity of glycolysis and a low activity of the pentose phosphate pathway.
C) It has a high activity of the oxidative phase of the pathway, low activity of the nonoxidative phase, and a low activity of glycolysis.
D) It has a high activity of the oxidative and forward nonoxidative phases of the pentose phosphate pathway, and a high activity of glycolysis.
