Transport Across Cell Membrane (Part 1)

Master Cellular Transport Mechanisms with Dr. Faiza Understand how substances cross the cell membrane. This session covers passive transport (simple and facilitated diffusion) and active transport (primary and secondary). See how the Na⁺/K⁺ pump maintains gradients and membrane potential. Review channels vs carriers, Fick’s law, and the patch clamp technique. Ideal for physiology and medical students preparing for exams. 🔬 Key Topics Covered: Passive Transport: Simple diffusion, facilitated diffusion, concentration gradients, factors in Fick’s law. Active Transport: Primary vs secondary, ATP use, symport and antiport. Na⁺/K⁺ ATPase: Steps, electrogenicity, role in cell volume and resting membrane potential, digitalis effect. Channels vs Carriers: Voltage-gated, ligand-gated, aquaporins; specificity, saturation, competition. Patch Clamp Basics: Cell-attached, whole-cell, inside-out, outside-out recordings. 🎓 Learning Objectives: Differentiate simple and facilitated diffusion using rate–concentration curves. Explain primary and secondary active transport with examples (Na⁺/K⁺ pump, SGLT, NCX). Relate membrane permeability, surface area, and distance to diffusion rate (Fick’s law). Apply concepts to clinical reasoning about edema, arrhythmias, and drug actions. 📚 Learning Resources: Phone: +92 310 7990649 Email: [email protected] Website: https://www.medicoseacademics.com/ Facebook:   / medicoseacademics   Instagram:   / medicoseacademics   YouTube:    / @medicoseacademics   Dr. Faiza Assistant Professor of Physiology MBBS (AIMC, lahore, Best Graduate) FCPS (Physiology) CHPE (Certificate in Health Professional Education) DHPE (Diploma in Health Professional Education) DHPE (Masters in Health Professional Education) MBA (Masters of Business Administration) MPH (Masters of Public Health) LinkedIn:   / faizaikram   Tags: Cellular Transport, Simple Diffusion, Facilitated Diffusion, Active Transport, Primary Active Transport, Secondary Active Transport, Sodium Potassium Pump, Na⁺/K⁺ ATPase, Osmosis, Fick’s Law, Ion Channels, Carrier Proteins, Voltage-Gated Channels, Ligand-Gated Channels, Patch Clamp, Membrane Potential, Electrochemical Gradient, Cotransport Symport, Countertransport Antiport, Medical Physiology
