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.
Carrier-mediated transport can be either passive or active, depending on the type of carrier protein involved. Passive carrier-mediated transport allows molecules to move down their concentration gradient without requiring energy input, while active carrier-mediated transport moves molecules against their concentration gradient using energy from ATP or an electrochemical gradient.
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
Carrier proteins are sometimes used during passive transport.
Active transport requires energy while passive transport does not.
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
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.
Carrier-mediated transport can be either passive or active, depending on the type of carrier protein involved. Passive carrier-mediated transport allows molecules to move down their concentration gradient without requiring energy input, while active carrier-mediated transport moves molecules against their concentration gradient using energy from ATP or an electrochemical gradient.
It can be either. A carrier pigeon is active whereas a malaria mosquito is passive.
it is active
It's either a passive or active transport.
Active transport occurs through carrier proteins that pump molecules against their concentration gradient using energy from ATP. These carrier proteins undergo conformational changes to transport molecules across the cell membrane.
Active transport requires assistance from membrane proteins. These proteins, such as ion pumps and carrier proteins, help move molecules against their concentration gradient, requiring energy input to drive the process.

Carrier proteins are sometimes used during passive transport.
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.
Carrier molecules in the plasma membrane are actually used for both active and passive transport of molecules. In active transport, carrier proteins use energy to move molecules against their concentration gradient, while in passive transport, carrier proteins facilitate the movement of molecules down their concentration gradient without the need for energy input.
Carrier proteins facilitate active transport by moving molecules or ions across a cell membrane against their concentration gradient. They require energy in the form of ATP to transport substances across the membrane.
