They are used in both, in passive the molecules move in , then change the shape then leave and the entering and leaving are both by diffusion.
in active transport molecules move in by diffusion, change the shape of the carrier protein, then because theyre moving into the cell where the molecule is in higher concentration energy is required to push the molecules out of the carrier proteins, this energy comes from ATP which is supplied to the carrier proteins.
Active
Passive just happens
if something needs to be carried then its being acted on... active...
active needs energy to
Carrier proteins can be involved in passive transport.
yes
Carrier mediated transport is not a type of a active transport......because it is a type of facilitate diffusion.
Carrier Proteins
A carrier protein (as opposed to a channel protein). An example of a carrier protein is the Na+/K+ pump.
Carrier proteins are sometimes used during passive transport.
Carrier Protein
Carrier proteins can use active or passive transport depending on what type of carrier protein it is (meaning what the protein transports). The form of passive transport that they use is facilitated diffusion. An example of active transport is the Sodium Potassium pump. Active transport requires ATP. Facilitated diffusion is used to transport polar molecules and ions that cannot directly cross the cell membrane. Facilitated diffusion doesn't require energy.
it is active
Active
It can be either. A carrier pigeon is active whereas a malaria mosquito is passive.
Carrier mediated transport is not a type of a active transport......because it is a type of facilitate diffusion.
cellular transport nop, is passive transport
It's either a passive or active transport.

substance to pass
Carrier proteins are sometimes used during passive transport.
Facilitated diffusion = down concentration gradient, it just uses a carrier protein (doesn't need energy)Active transport =goes UP concentration gradient with the help of a carrier protein and ENERGY
