The mannitol would enter the cell via
A. the energy contained within a molecule of phosphoenol pyruvate (PEP)
B. the energy contained within a molecule of ATP
C. the energy contained within a molecule of NADH
D. the energy contained within a molecule of O2
E. osmosis
Homework Answers
E. Osmosis
Mannitol is a osmotic diuretic used by patients with kidney failure. It is also used to reduce the swelling of eye and regions near the brain.
Mannitol inhibits water and sodium reabsorption thus increasing the urine concentration. They increase the osmolarity of blood and renal filtrate.
It increases the blood flow to kidney by expanding extracellular fluid and plasma volume.Thus the cortical medullary gradient is removed.Thus concentartion of urine by loop of henle is prevented. In eyes and regions around brain it acts by reducing intraocular and inntra cranial pressure.

If a cell does not have mitochondria, it cannot harvest the entire energy stored in a molecule of glucose? A)True B)False Phosphofructokinase is an enzyme that is important for the breakdown of the glucose molecule to generate ATP. In regards to that, when the ATP levels are high, the phosphofructokinase is inhibited. What do you expect to happen to the enzyme when the levels of ATP within the cell drop? 1.The enzyme will be activated. 2.The enzyme will be deactivated....
