% Change in Potato
Core Mass
Groups of students in a biology class conduct an experiment to explore the movement of water into and out of plant cells. Each group makes six potato
cores and mneasures the initial masses of the cores. The groups submerge the potato cores in sucrose solutions of differing concentrations that range
from 0.0 M to 1.0 M. After one hour, each group removes the potato cores from the solutions and measures the final masses of the cores. The initial and
final masses of the potato cores are used to calculate a percent change in mass for each core to account for differences in the initial masses. The students
generate a graph using the average percent change in mass for all the groups in the class for each solution.

Let's think about why scale (l) matters for mixing.

- © Macmillan Learning A outside → Ainside, is 10.9 kJ/mol at 25°C. Consider a uniport system where a carrier protein transports an uncharged substance A across a cell membrane. Suppose that at a certain ratio of [A] inside to [A] outside, the AG for the transport of substance A from outside the cell to the inside, What is the ratio of the concentration of substance A inside the cell to the concentration outside? [A]inside [A] outside -81.28 Incorrect Answer Choose the true statement about the transport of A under the conditions described. Decreasing the concentration of the uniport protein in the membrane will cause AG to become a smaller positive number. Because AG is positive, the ratio [A] inside/[A] outside must be less than one. Increasing [A] outside will cause AG for movement of Aoutside to Ainside to become a larger positive number. Movement of Ainside to Aoutside will be spontaneous.
