What is the difference between diffusion and active transport refer to cell membrane and its properties?

Diffusion requires no energy as it follows the electrochemical gradient. Active transport requires energy (ATP), as it works against the electrochemical gradient.

What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
Facilitated diffusion across a biological membrane requires what?
transport proteins
What is meant by passive transport of material across a membrane?
"Passive" mean that it does not require energy, therefore the passive transport of material across the membrane means that it can transport the material (cells or whatever) without the function of energy across the membrane.
What process occurs in a cell membrane?
Electron Chain
How do substances move through cell membrane?
Active transport - When the cell uses energy to move the substance across a partially permeable membrane. Usually done when What_are_three_ways_for_materials_to_move_in_and_out_of_cellsagainst a concentration gradient or water potential.Diffusion/Passive transport - When the substance moves across a partially permeable membrane down a concentration gradient or What_are_three_ways_for_materials_to_move_in_and_out_of_cellspotential. (Method takes no energy).Osmosis - The movement of water down a water potential across a partially permeable membrane. (This uses no energy).
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 a specialized form of diffusion and diffusion is a type of passive transport.?
membrane
Is a specialized form of diffusion and diffusion is a type of passive transport?
membrane
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 types of movement through a membrane?
Osmosis, diffusion, facilitated diffusion, active transport
What cause certain things to enter cell?
Things can enter the cell through various processes, such as osmosis, diffusion and active transport. Passive transport (diffusion/osmosis) occurs because of a difference in concentration across the membrane.
What type of plasma membrane transport is used for exchange?
Diffusion
What is meant by faciliated diffusion?
Facilitated diffusion (or facilitated transport) is a form of passive transport that is facilitated by transport proteins. Most often it is used to transport polarized molecules (such as glucose and amino acids) across the cell membrane.
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
Facilitated diffusion across a biological membrane requires what?
transport proteins
What type of plasma membrane transport is used for gas exchange?
Diffusion
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
