Endocrine System Signaling Pathways
Simulate hormone cell signaling. Compare lipid-soluble steroid diffusion acting as a nuclear transcription factor versus water-soluble peptide binding that triggers a massive cAMP secondary messenger cascade.
Membrane Potential & Nernst Equation
Calculate the resting membrane potential using the Goldman-Hodgkin-Katz equation. Visualize Na⁺ and K⁺ leak channels, actively tweak permeabilities, and trigger simulated action potentials.
Immune System Clonal Selection
Simulate the Lock-and-Key mechanism of the immune system. Inject various pathogen epitopes and observe how massive clonal expansion and antibody production is triggered only when a naive B-Cell matches the exact molecular geometry.
Kidney Nephron Countercurrent Multiplier
Visualize the complex osmotic gradients of the Loop of Henle. Observe how the active transport of NaCl in the ascending limb drives the passive reabsorption of H2O in the descending limb and collecting duct via ADH regulation.
