What are the different types of cell transport?
active transport -transport against concentration gradient that requires chemical energy passive transport- requires no energy at all
What proteins are used in active and passive transport?
cell membrane
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 cells use active transport?
Energy, versus passive in which energy is not used.
What perform active transport cells use?
Energy, versus passive in which energy is not used.
What are the two general types of transport used by cells to transport materials in and out of the cell?
The two general types of transport used by cells are passive transport, which does not require energy and includes processes like diffusion and osmosis, and active transport, which requires energy and involves processes like protein pumps and vesicle transport.
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.

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.
What cells use active transport?
Energy, versus passive in which energy is not used.
What perform active transport cells use?
Energy, versus passive in which energy is not used.
To perform active transport cells use what?
Energy, versus passive in which energy is not used.
Why is the term 'equilibrium' used with passive but not active transport?
The term "equilibrium" is used with passive transport because it describes a state where there is no net movement of molecules across a membrane due to equal concentration on both sides. In active transport, energy is used to move molecules against their concentration gradient, so equilibrium is not reached as the process continues to pump molecules in or out of the cell.
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.
Is oxygen a passive transport or an active transport?
They move via passive transport. They move by diffusion. It's only active transport if A) the cell is too big or not fatty enough to move through the membrane and needs help or B) is making the molecules move unnaturally (low to high). Osmosis is also passive transport, but only is used when referring to the movement of water.
