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 facilitate both passive and active transport across a cell membrane. In passive transport, carrier proteins help molecules move down their concentration gradient without the need for energy input. In active transport, carrier proteins use energy to transport molecules against their concentration gradient.
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.
Does simple diffusion require transport proteins?
No, simple diffusion does not require transport proteins. It is a passive process where molecules move from an area of higher concentration to an area of lower concentration directly through the lipid bilayer of the cell membrane. Transport proteins are involved in facilitated diffusion and active transport.
Transport proteins play a role in both?
Transport proteins play a critical role in facilitating the movement of molecules across biological membranes, such as ions, nutrients, and waste products. They help maintain cellular homeostasis by regulating the flow of substances into and out of the cell. Transport proteins can be passive (facilitated diffusion) or active (requiring energy).
How is facilitated diffusion similar to both passive transport and active transport?
Facilitated diffusion is similar to passive transport in that it does not require energy input from the cell. It is similar to active transport in that it involves the use of carrier proteins to move molecules across the cell membrane.
Is carrier proteins passive transport or active transport?
Carrier proteins can facilitate both passive and active transport across a cell membrane. In passive transport, carrier proteins help molecules move down their concentration gradient without the need for energy input. In active transport, carrier proteins use energy to transport molecules against their concentration gradient.
Is diffusion and osmosis both active transport?
no they are passive transport

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.
Is mineral movement into plant root part of an active transport or passive transport?
Both
Is water an active or passive transport?
Water can use both passive and active transport mechanisms. Passive transport involves movement of water molecules across a membrane without the need for energy, while active transport involves the use of energy to move water molecules against their concentration gradient.
Do passive transport mechanisms use integral proteins to move substances through membranes?
Yes, passive transport mechanisms like facilitated diffusion use integral proteins to help move substances across membranes. These integral proteins act as channels or carriers that facilitate the movement of molecules down their concentration gradient without requiring energy input from the cell.
Is diffusion and osmosis types of active tranport?
No they're both passive transport
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.
