Why do transport proteins require energy to function in active transports?
because
What are the four types of proteins found in the cell membrane?
Actually, bilipid "heads" form the layers of the membrane, but there are carrier proteins that transport objects into and out of the cells. These carrier proteins use either active or passive transport to get objects across the membrane. Active transport uses energy, while passive transport doesn't need to use energy to get items across. Hope this helps!!!
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 kind of molecules are moved in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
What type of carrier proteins use energy and act as a pump to move nutrients into a root cell?
Type your answer here... active transport
What is the role of transport proteins in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.

Which form of transport across the cell membrane does not require energy but a carrier protein?
Facilitated transport.
Does active transport require transport proteins?
Yes, active transport requires carrier proteins in order to function. These require ATP to carry things in and out of the cell.

What are examples of passive transport and active transport?
Proteins that carry out passive transport include channel proteins and carrier proteins. Passive transport is "passive" because it does not use energy. The use of passive transport is also called "facilitated diffusion." Proteins that carry out passive transport includes the proton pump and the sodium-potassium pump; these require energy to function.

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.
What kind of molecules are moved in active transport?
Active transport requires energy, unlike passive transport. The carrier proteins in active transport act as a "pump" ( fueled by ATP) to carry/attach themselfves to useful proteins for the cell.
Describe the role of carrier proteins during active transport?
they work as a catalysator for the transportation. They lower the nessesary energy for a transport to start. This can in many cases only be achieved by highly specifically adapted carriers, which in cells is mostly proteins.
A form of passive transport that uses transport proteins-?
Diffusion (passive transport) needs no energy to take place, and therefore no need for transport or carrier protiens. Active transport uses carrier protiens, as the cell needs to work against a concentration gradient. This requires energy. Diffusion can take place outside of cells Active transport can't take place outside of cells.
Why is facilitated transport a passsive transport?
Facilitaed Transport is a passive transport because its the same thing. the process is carried out by an enzyme-like carrier. Since it doesn't require energy it is passive
