Answer:

concentration gradient

Explanation:

concentration refer to number of ions on either side of membrane

gradient :difference in concentration on both sides of membrane

on this basis:

one side of membrane: higher concentration of h+ ion

other side of membrane :lower concentration f h+ ions

pumps transport ions from higher concentration side to lower concentration side of membrane

In an experiment, you measure the concentration of a polar molecule inside and outside a cell. You find that the concentration i

<h2>The correct answer is: d).</h2>

Explanation:

Active transport can be defined as the process by which molecules are transported from a region where the concentration of the molecules is low to a region where the concentration of molecule is high across a selectively permeable membrane.
Here, the molecules are transported up or opposite to their concentration gradient and so the process requires the expenditure of energy in the form of ATP or Adenosine Triphosphate.
In the given question, it is said that the concentration of a polar molecule is high inside the cell initially.
But still with time the concentration of the polar molecule continues to increase inside the cell.
This is accompanied by the expenditure of energy in the form of ATP as concentration of ATP inside the cell is found to drop gradually.
Hence, the given hypothesis describes the process of an Active Transport.
