What are the similarities between facillitated transport and active transport?
Both facilitated transport and active transport involve the movement of molecules across a cell membrane with the help of carrier proteins. However, facilitated transport does not require energy input from the cell, while active transport does require energy in the form of ATP. Both processes are specific and selective in what molecules they transport across the membrane.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
Does active transport require energy to move a molecule across a cell membrane?
Yes, in a matter of fact the nucleus gets the information because the object passes through the cell membrane and brings the information over to the nucleus.
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.
Which membrane activities require ATP?
Active transport... Not anything passive though.
What membrane activities require energy from ATP?
Any kind of active transport.
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.
What process require ATP energy to transport materials across a selectively premeable membrane into the cell?
active transport
What require the use of energy to move a molecule across a cell membrane?
Active transport
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.
How does facilitated transport differ from active transport in terms of the energy requirements and mechanisms involved in moving molecules across a cell membrane?
Facilitated transport and active transport are two ways molecules can move across a cell membrane. Facilitated transport does not require energy from the cell, while active transport does require energy in the form of ATP. Facilitated transport uses carrier proteins to help molecules move across the membrane, while active transport uses pumps to move molecules against their concentration gradient.
What is the difference between active transport and osmosis?
Osmosis is the diffusion of water across a membrane, and does not require the input of energy. Active transport requires energy input.
What are the similarities between facillitated transport and active transport?
Both facilitated transport and active transport involve the movement of molecules across a cell membrane with the help of carrier proteins. However, facilitated transport does not require energy input from the cell, while active transport does require energy in the form of ATP. Both processes are specific and selective in what molecules they transport across the membrane.
How are active transport and passive transport different from each other?
Active transport requires energy input to move substances across a membrane against their concentration gradient, while passive transport does not require energy as it moves substances along their concentration gradient. Active transport is selective and requires specific transport proteins, while passive transport occurs through simple diffusion or facilitated diffusion.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
All transport through the cell membrane can be classified as?
passive or active transport. Passive transport does not require energy input and includes processes like diffusion and facilitated diffusion. Active transport requires energy input and includes processes like primary active transport and secondary active transport.
