An artificial membrane separates two sides of a beaker. The left side contains 50 glucose molecules and the right side contains 100 fructose molecules. If you add channels to the membrane for glucose molecules but do not add any for fructose molecules and then wait for a while, which will more likely be true? A. The 50 glucose molecules will have moved from the left side to the right side of the beaker, because the channels allowed them to cross the membrane.
B. The 50 glucose molecules will not have moved to the right side of the beaker, because there are already 100 fructose molecules on the right side of the beaker.
C. About 25 glucose molecules will be on the right side of the beaker, and 25 will be on the left side of the beaker.
D. Both sides of the beaker will contain approximately equal numbers of glucose and fructose molecules.

C. About 25 glucose molecules will be on the right side of the beaker, and 25 will be on the left side of the beaker.

Explanation:

This question is describing the process of solute movement. According to the question, two sides of a beaker contains 50 molecules of glucose on its left side and 100 molecules of fructose on it's right side, both separated by an artificial membrane.

Naturally, solutes will move from a region of higher concentration to a region of lower concentration via a membrane in a process called DIFFUSION. However, since CHANNELS were added to the membrane for glucose molecules, they will facilitate the movement of glucose from the left side to the right side until there is an equal concentration of glucose molecules on both sides of the membrane.

Hence, About 25 glucose molecules will be on the right side of the beaker, and 25 will be on the left side of the beaker
