What substances need a protein?
Proteins are essential for the body to function properly. Many substances require proteins for their production, such as enzymes, hormones, antibodies, and structural components like collagen. Additionally, proteins are needed for transport and signaling within the body.
What is the difference between active transport and pass transport?
Pass transports require no energy and active requires energy. Osmosis is when it travels through water.
What are membrane structures that function in active transport?
Protein pumps, such as the sodium-potassium pump and the proton pump, are membrane structures that function in active transport by moving ions against their concentration gradients across the cell membrane. These pumps require energy, usually in the form of ATP, to transport substances.
what two methods of transport require a transport protein?
Two methods of transport that require a transport protein are facilitated diffusion and active transport. Facilitated diffusion involves the movement of molecules across a cell membrane through specific transport proteins, down their concentration gradient without the use of energy. Active transport, on the other hand, uses transport proteins to move substances against their concentration gradient, requiring energy in the form of ATP.
What types of cell transport do expend energy?
Active transport processes, such as primary active transport, secondary active transport, and vesicular transport, require the cell to expend energy in the form of ATP. These processes enable the movement of molecules or ions against their concentration gradients or across membranes.
What are a series of carrier proteins?
Active transport involves carrier proteins. Carrier proteins bind themselves to particles and transport them to highly concentrated areas within a cell.Facilitated diffusion and active transport require carrier proteins.
Does active transport require transport proteins?
Yes, active transport does require transport proteins. These proteins use energy to move molecules against their concentration gradient, typically from an area of low concentration to high concentration. This process is essential for maintaining cellular homeostasis.
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.

Pass transports require no energy and active requires energy. Osmosis is when it travels through water.
What process changes the shape of transport proteins when a particle binds with it?
The process that changes the shape of transport proteins when a particle binds to it is called conformational change. This change in shape allows the protein to either open a channel for the particle to pass through or undergo a rotational movement to transfer the particle across the membrane.
What are membrane structures that function in active transport?
Protein pumps, such as the sodium-potassium pump and the proton pump, are membrane structures that function in active transport by moving ions against their concentration gradients across the cell membrane. These pumps require energy, usually in the form of ATP, to transport substances.
Are diffusion and osmosis passive or active transports?
Diffusion and osmosis are passive and do not require energy.
Which form of transport across the cell membrane does not require energy but a carrier protein?
Facilitated diffusion does not require energy but relies on carrier proteins to transport molecules across the cell membrane. The carrier proteins assist in the movement of specific molecules down their concentration gradient.
How is faciliated transport similar to active transport?
Both facilitated transport and active transport require the substance that passes the membrane to pass through intermembrane proteins. However, unlike active transport, facilitated transport does not require ATP because it is not actively going against the concentration gradient.

Are carrier proteins active or passive transport?
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.
