Example:
Imagine trying to push a heavy shopping cart uphill at the grocery store parking lot. Just as you need to exert effort and energy to move the cart against gravity, cells use energy to transport materials across their membranes against a concentration gradient. In this analogy, the shopping cart is like the materials being moved, the hill represents the cell membrane, and the energy you exert is similar to the energy cells use during active transport to move substances from a lower to a higher concentration.
Practice Version
Active Transport: The movement of materials through the cell membrane using energy. Active transport. Active transport is when cells use energy to move substances against their natural flow through the membrane.
