Electrochemical Gradient

The video tutorial explains diffusion and its role in cellular processes, highlighting how molecules move from high to low concentration due to kinetic energy and Brownian motion. It introduces the concept of electrochemical gradients, crucial for understanding complex biological systems like resting potential and action potential in neurons. Through simulations, the video demonstrates diffusion using food coloring and explores ion movement through channels, emphasizing the balance between chemical and electrical gradients. The tutorial also covers electrochemical equilibrium, potential, and the use of the Nernst equation to calculate voltage, supported by simulators.
