Fick's First Law (1): Diffusion, Flux, and Concentration Gradients

The video tutorial explains Fick's First Law of diffusion, emphasizing that molecules move from areas of high concentration to low concentration. It uses a graph to illustrate this concept, showing how diffusion occurs at different points. The tutorial also discusses the concentration gradient and how it affects the direction of net flux. Through examples, it demonstrates how to determine the direction of diffusion graphically and mathematically.

What does Fick's First Law of Diffusion state in layman's terms?

What is the relationship between concentration and diffusion in biological systems?

How does the concentration gradient affect the direction of diffusion?

Explain the significance of the slope of the graph in relation to diffusion.

What happens to the net flux at a point where the slope is zero?

Describe how you would determine the direction of net flux graphically.

How can you mathematically estimate the slope of a concentration function?
