you ar telling lies you dont know anything about bloody mary lies lies lies
No, constant gradient does not directly relate to passive transport. Passive transport is the movement of molecules across a membrane without the use of cellular energy, while constant gradient refers to a consistent change in concentration over a distance. However, the presence of a constant gradient can facilitate passive transport by driving the movement of molecules down their concentration gradient.
Active transport requires energy; passive transport does not.

Active transport requires energy while passive transport does not.
Carrier proteins facilitate passive transport of molecules across a membrane by changing its shape, by using ATP, to allow a substance to pass through the membrane.
Carrier proteins facilitate the passive transport of molecules across a membrane by binding to specific molecules on one side of the membrane and changing shape to transport the molecules across to the other side. This process does not require energy and is driven by the concentration gradient of the molecules.
Transport proteins such as ion channels and carrier proteins are used in both active and passive transport processes. Ion channels move ions down their concentration gradient through passive transport, while carrier proteins can facilitate passive transport by allowing molecules to move along their concentration gradient, or active transport by requiring energy to transport molecules against their concentration gradient.
