What else can I help you with?
There are two main ways in which molecules are transported into and out of cells - active transport and passive transport. Which of the following statements is true of passive transport?
Carrier proteins are sometimes used during passive transport.
What perform active transport cells use?
Energy, versus passive in which energy is not used.
Which proteins are used in active and passive transport?
In active transport, proteins like pumps (such as Na+/K+ ATPase) are commonly used to move molecules against their concentration gradient, requiring energy in the form of ATP. Passive transport commonly involves proteins like ion channels and carrier proteins that facilitate the movement of molecules down their concentration gradient without requiring energy input.
What are the proteins used in active transport called?
Proteins used in active transport are called transport proteins. These proteins are responsible for moving molecules or ions across a cell membrane against their concentration gradient, requiring energy in the form of ATP.
Is a carrier protein an active transport or a passive transport?
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.
What proteins are used in both active and 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.

Is carrier proteins passive transport or active transport?
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 transport commonly involves proteins like ion channels and carrier proteins that facilitate the movement of molecules down their concentration gradient without requiring energy input.
Carrier molecules in the plasma membrane are only required for active transport?
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.
Is used during active transport but not passive transport?
ATP (adenosine triphosphate) is used during active transport but not passive transport. Active transport requires energy to move substances against their concentration gradient, while passive transport relies on diffusion to move substances down their concentration gradient without the need for energy.

When are active and passive transport and their types used?
Active transport uses energy in the form of ATP. Active can force electrons against the electron gradient as in the electron transport chain. Passive transport does not use energy and an example of passive transpost is osmosis.
What is passive transportation?
Passive transport is a means of moving biochemicals, and other atomic or molecular substances, across membranes. Unlike active transport, this process does not involve chemical energy. Passive transport is dependent on the permeability of the cell membrane, which, in turn, is dependent on the organization and characteristics of the membrane lipids and proteins. The four main kinds of passive transport are diffusion, facilitated diffusion, filtration and osmosis. An example would be osmosis; in osmosis, water molecules move from an area of high concentration to an area of low concentration. Carrier proteins are sometimes used during passive transport.
