Active transport is defined by its need for metabolic energy.
– Indirect use of ATP. The gradient created by primary active transport (e.g., Na⁺ gradient) powers another molecule’s movement. ATP isn’t used directly, but without ATP to build the gradient, secondary transport fails. does active transport use atp
Here, the transport protein does touch ATP directly. Instead, it uses the "potential energy" created by primary active transport. Active transport is defined by its need for metabolic energy
In active transport, ATP is used to drive the movement of molecules or ions against their concentration gradient. There are two main types of active transport: ATP isn’t used directly, but without ATP to
