A Cell Is Placed in a Solution of Large Nutrient

question 23

Multiple Choice

A cell is placed in a solution of large nutrient molecules tagged with a red dye.Soon the cell is dark red,showing a concentration of the nutrient much higher than the external solution.We add a reagent that blocks the use of ATP.What result would you expect from this experiment?

• A)The nutrient would continue to rapidly enter the cell by diffusion because as a nutrient it is constantly being used in cell metabolism,so the cell will get redder.
• B)The color will remain the same since all future transfer will stop.
• C)The color will fade as the import of the nutrient stops and diffustion evens the concentrations as it moves the nutrient molecules out of the cell.
• D)The cell will continue to get darker since the import of the nutrient does not involve ATP.
• E)The cell will die without access to ATP.
