Some are passive (e.g. melanin) and some are active (e.g. actin, myosin).

B passive transport i think This is cassidy evans from ramah high school
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.
The protein pump is active in its function.
It's either a passive or active transport.
The movement of ions through a protein pump is an active process.
Depends if it goes into the cell or out of the cell whether it is passive or active. Yes.
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.
passive
Passive transport is the movement of molecules across a cell membrane without requiring energy, such as diffusion and osmosis. Active transport, on the other hand, requires energy to move molecules against their concentration gradient, typically using protein pumps or transporters.
active and passive
== == "English grammer active and passive voice change from active to passive .
Passive is to change as active is to affect.
is a thermocouple an active or passive transducer?-why?
