An example of passive transport would be the process of osmosis (water diffusing between a membrane-- from an area of high concentration to an area of low concentration). It is known as passive transport because no energy is needed in order to move the water across the membrane. When no energy is needed to move the substance it is considered passive transport. On the other hand, when energy IS needed to transport molecules or substances across a membrane it is referred to as active transport. An example of this would be a calcium pump located in the lipid bilayer of a plasma membrane which can transport potassium (K+) ions across it. Energy is needed in order to move those potassium ions across the membrane, and therefore is referred to as active transport.
Active transport is selective, and passive transport is not.
Diffusion is passive, it happens everywhere whether living things are involved or not. It results from the natural thermal motion of particles.
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
Active transport is the process of molecules being moved across a membrane using energy. Passive transport moves the molecules without using energy.
Active because The subject (the dog) caught the object (the ball). The passive term would be, the ball was caught by the dog.
Active - as it involves the contraction of muscles.
active
Passive transport and active transport are transport of materials across membranes. Passive requires no energy, while active does.
Active transport requires energy; passive transport does not.
Active transport requires energy; passive transport does not.
Active transport requires energy; passive transport does not.
Active transport requires energy while passive transport does not.
passive
passive
it is an ACTIVE transport.
Active transport requires energy, passive transport does not.
It has is in the name. Active Transport
Passive Transport, i think.
