What is the primary role of Glucose 6-phosphatase in mammalian liver cells, and how do its products affect blood glucose levels?
A: It catalyzes the synthesis of glucose 6-phosphate, thereby decreasing blood glucose.
B: It catalyzes the breakdown of glucose 6-phosphate into glucose and inorganic phosphate, which are then transported out of cells, increasing blood glucose.
C: It catalyzes the breakdown of glucose into glucose 6-phosphate, thereby decreasing blood glucose.
D: It catalyzes the synthesis of glycogen, thereby stabilizing blood glucose.
Explanation
The text states that Glucose 6-phosphatase catalyzes the breakdown of glucose 6-phosphate into glucose and inorganic phosphate Pi . These products are then transported out of liver cells into the blood, increasing the blood glucose level.
