A cell is placed in a solution of large carbohydrate 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 become more red.
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 diffusion 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.
ATP
Adenosine triphosphate, a molecule that carries energy within cells.
Carbohydrate Molecules
Organic compounds made up of carbon, hydrogen, and oxygen atoms, serving as a major source of energy for most organisms.
Nutrient
Substances in food that provide energy or contribute to cell structure and function.
- Understand how cells utilize ATP in transport mechanisms and the consequences of ATP inhibition on cellular processes.

Final Answer :
B
Explanation :
Blocking ATP use inhibits active transport mechanisms that concentrate substances inside the cell, so the nutrient import stops, and the color remains the same.
