Question
The incredible catalytic power of enzymes can perhaps best be appreciated by imagining how challenging life would be without just one of the thousands of enzymes in the human body. For example, consider life without fructose-1,6-bisphosphatase, an enzyme in the gluconeogenesis pathway in liver and kidneys, which helps produce new glucose from the food we eat: Fructose-1,6-bisphosphate + H20 → Fructose-6-phosphate + P; The human brain requires glucose as its only energy source, and the typical brain consumes about 120. g (or 480. calories) of glucose daily. Ordinarily, two pieces of sausage pizza could provide more than enough potential glucose to feed the brain for a day. According to a national fast-food chain, two pieces of sausage pizza provide 1290 calories, 47.0 % of which is from fat. Fats cannot be converted to glucose in gluconeogenesis, so that leaves 606 calories potentially available for glucose synthesis. The first-order rate constant for the hydrolysis of fructose-1,6-bisphosphate in the absence of enzyme is 2.00×10-20 sec-1 a Calculate the moles of glucose that could be made from the two pieces of sausage pizza assuming 100 % conversion of the available calories. (The molar mass of glucose is 180. g/mol) Moles of glucose = moles
