In what ways are active transport and facilitated diffusion similar?
Active transport and facilitated diffusion are similar in that they both involve the movement of molecules across a cell membrane, but they differ in that active transport requires energy input from the cell, while facilitated diffusion does not.
What is it called when materials move from lower to higher concentration?
Specifically Diffusion, but it is also 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.
What 3 ways can substances enter and leave a cell?
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
Does active transport rely on the process of diffusion?
Yes except, diffusion is a passive process (no energy is required) whereas active transport requires energy. this is because it is moving UP then concentration gradient whereas diffusion moves DOWN it
What is the way the active transport differs from diffusion?
Active transport uses energy while diffusion does not
Is diffusion through ion channels a form of active transport?
Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
Are osmotically active substances simple diffusion or active transport?
simple diffusion.
What are Vesicle mediated transport is a type of?
facilitated diffusion, secondary active transport and active transport
Is diffusion an example of active transport or passive transport?
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
Is channel-mediated diffusion a form of active transport?
Yes, when channels are specific for the structures of individual molecules it is active transport. Active transport cannot occur if the energy they are moving is not of the same type, like glucose cannot move calcium.
What is the main way that active transport differs diffusion?
ATP is required for active transport.
Is diffusion and osmosis both active transport?
no they are passive transport
Is facilitated diffusion active?
No. Facilitated diffusion is a type of passive transport.
In what ways are active transport and facilitated diffusion similar?
Active transport and facilitated diffusion are similar in that they both involve the movement of molecules across a cell membrane, but they differ in that active transport requires energy input from the cell, while facilitated diffusion does not.
What is it called when materials move from lower to higher concentration?
Specifically Diffusion, but it is also active transport
Is diffusion an act of active transport?
No, diffusion is not an act of active transport. Diffusion is a passive process where molecules move from an area of high concentration to an area of low concentration, without the input of energy. Active transport, on the other hand, requires energy to move molecules against their concentration gradient.
