Understanding Active Transport in Cells

The video tutorial explains the concept of active transport by comparing it to removing smoke from a kitchen using a fan. It highlights how active transport involves moving materials from low to high concentration, requiring energy, unlike osmosis. An analogy of biking uphill is used to illustrate the energy needed for active transport.
