Question 19
Three molecules (A, B, C) with the following chemical formulas examined for their rates of diffusion through agar. The molecules are:
A C6H12O6
B C4N201H10
C C6N2O2H10
Which of the three molecules will migrate the furthest in a set amount of time?
B
They will all migrate the same distance in the same amount of time
None of the molecules will migrate without the addition of outside energy
A
C
B
They will all migrate the same distance in the same amount of time
None of the molecules will migrate without the addition of outside energy
A
C
Explanation / Answer
Agar gel, when solidified, has pores small enough for small molecules like antibiotics and solvents to diffuse through it. However, molecules like C6H12O6, C4N2O1H10, and C6N202H10 are much too large to pass through the pores of the gel. These molecules will not be able to diffuse through the gel.
Thus, the correct answer is: none of the molecules will migrate without the addition of outside energy.
