what is the difference between active transport and diffusion?

What is the difference between diffusion and active transport? Diffusion is the movement of particles from a high concentration to a low concentration. ... Active transport is the movement of particles from an area of low concentration to an area of high concentration. This process requires energy (ATP).

Diffusion is the movement from a high concentration of molecules to a low concentration of molecules. ... Moving molecules with cell energy is called active transport. The cell energy is the ATP made in the mitochondria.

Which best describes the difference between osmosis and diffusion? Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration. ... Particles are moving into and out of the cell, but their concentrations remain stable.

Movement Across a Membrane and Energy There are two major ways that molecules can be moved across a membrane, and the distinction has to do with whether or not cell energy is used. Passive mechanisms like diffusion use no energy, while active transport requires energy to get done.

There are two major types of cell transport: passive transport and active transport. Passive transport requires no energy. It occurs when substances move from areas of higher to lower concentration. Types of passive transport include simple diffusion, osmosis, and facilitated diffusion.

1 Answer. simple diffusion moves molecules down concentration gradient while active transport takes them against concentration gradient. ... Simple diffusion happens directly through the cell membrane, while active transport through carrier proteins.

Active transport requires chemical energy because it is the movement of biochemicals from areas of lower concentration to areas of higher concentration. On the other hand, passive transport moves biochemicals from areas of high concentration to areas of low concentration; so it does not require energy.

In facilitated diffusion, ions, sugars, and salts are transported across the membrane. In active transport, ions, sugars, and salts are also transported. The second similarity is that both facilitated diffusion and active transport use proteins as their means of transporting their materials to and from the cell.

Osmosis is movement of water molecules from an area of their higher concentration to area of their lower concentration through a semipermeable membrane. Active transport is movement of molecules from an area of their lower concentration to area of their higher concentration using energy in form of ATP by pump proteins.

Differences: Passive Transport (or Diffusion) moves ions from high concentration to low, using no metabolic energy. Active Transport moves ions from low concentration to high, using metabolic energy in the form of ATP.

In terms of rates and speeds, effusion and diffusion are quite similar. The difference between the two is that diffusion is the spreading out of a substance within a dispersing medium, and effusion is when a substance escapes through a tiny pinhole, or other hole.

This process is called passive transport or facilitated diffusion, and does not require energy. The solute can move "uphill," from regions of lower to higher concentration. This process is called active transport, and requires some form of chemical energy.

Transport in cells Diffusion is the movement of particles from a high to lower concentration. ... Active transport moves particles from low to higher concentration.

Active transport the molecules move from a lower concentration to a higher concentration. Passive transport the molecules move from a higher concentration to the lower concentration.

This differences leads to other aspects of these two types of transport to be different as well. This difference is that active transport needs energy, while facilitated diffusion does not need energy. The energy that active transport uses is ATP (adenosine triphosphate).

Simple Diffusion. movement of a solute from an area of high concentration to an area of low concentration. Passive Transport. requires NO energy, movement of molecules from high to low concentration, moves with the concentration gradient.

Diffusion is the movement of particles down their concentration gradient, meaning they flow from places of high concentration to places of low concentration. When the substance diffusing is water, the process is called osmosis. ... The two main types of diffusion are passive diffusion and facilitated diffusion.
