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
What are the differences between facilitated diffusion and active transport in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion is a passive process that uses carrier proteins to transport molecules across the cell membrane along their concentration gradient, while active transport is an energy-dependent process that uses ATP to move molecules against their concentration gradient through protein pumps.
What are the key differences between active transport and facilitated diffusion in terms of their mechanisms of movement across cell membranes?
Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules move down their concentration gradient across the cell membrane.
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 is a major difference between facilitate diffusion and active transport?
Active transport moves substances against the concentration gradient.
What is the way the active transport differs from diffusion?
Active transport uses energy while diffusion does not
Differences between primary and secondary active transport?
In primary active transport, the transport protein gets phosphorylated; in secondary active transport, the transport protein is not phosphorylated
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).
Differences between active transport and facilitated diffusion?
Active transport requires energy in the form of ATP to move molecules against their concentration gradient, while facilitated diffusion uses carrier proteins to move molecules down their concentration gradient without requiring energy. Active transport can move molecules against their concentration gradient, while facilitated diffusion can only move molecules down their concentration gradient.
What is the main way that active transport differs diffusion?
ATP is required for active transport.
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.
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.
