Inside every cell, constant movement keeps life going. In this episode of Deep Dive, we uncover how substances cross biological membranes—from simple diffusion and osmosis to complex active transport powered by cellular energy. 💧⚡ Learn how membrane proteins act as gates, pumps, and channels, ensuring that nutrients, ions, and signals move exactly where they’re needed. Why can some molecules pass freely while others require energy? And how does this microscopic traffic control sustain life? Join us as we explore the fascinating science of cellular transport! 🔬🚀
