- If there was India Ink added to a culture of Paramecium caudatum, it would increase the average number of food vacuoles because India ink contains no sugar or nutrients and the formation of food vacuoles would be the first stage in the metabolic process when digesting nutrient-rich particles. If Sugars (sucrose or mannitol) were added to this culture to modify extracellular solute concentration, what effect would we see in the microscopic in regards to the number of food vacuoles and will the amount of food vacuoles change over time? Could sugars have other effects beyond altering solute concentration?

- Does concentration of xylulose-5-phosphate increase in cells after eating rice? ExplainO Att Intestinal epithelial cells pump glucose into the cell against its concentration gradient using the Nat-glucose symporter. Recall that the Nat concentration is significantly higher outside the cell than inside the cell. The symporter couples the "downhill" transport of two Nat ions into the cell to the "uphill" transport of glucose into the cell. If the Nat concentration outside the cell ([Na lout) is 161 mM and that inside the cell ([Na* Jm) is 17.0 mM, and the cell potential is -50.0 mV (inside negative), calculate the maximum energy available for pumping a mole of glucose into the cell.
