Phospholipids Between Us: (Part 2) Transport through Cell Membranes Preview CT-STEM

Exploration 1:

Plot a curve on the graph paper provided to you based on the values entered in Table 1, Table 2 and Table 3 for ‘Time’ on the X-axis and the ‘Number of chloride ions outside the cell’ on the Y-axis.

Questions

Please answer the questions below.

Question 4.1

Question 7: How does the increase of concentration affect the rate of diffusion? Explain with the help of the curves you plotted.

Question 4.2

Question 8: How does the presence of another type of molecule affect the rate of diffusion? Explain with the help of the curves you plotted.

Question 4.3

Question 9: In the third and last simulation, if the concentration of sodium ions is increased, how will it affect the rate of diffusion of chloride ions?
