What else can I help you with?
Does facilitated diffusion require energy for the movement of molecules across the cell membrane?
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
What types of diffusion do not require energy?
Diffusion does not require energy. Diffusion is that natural tendency of particles to move from an area of high concentration to an area of low concentratrion and therefore, it does not need energy to occur.
During the process of diffusion what happens?
During diffusion, molecules move from an area of higher concentration to an area of lower concentration, in order to reach an equilibrium. This movement occurs randomly, driven by the kinetic energy of the molecules. Diffusion does not require energy input from the cell.
What is the movement of molecules from areas high concentration to areas of low concentration?
Diffusion.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
Which transport does not require cell energy?
Diffusion is per definition a passive transport process.
Does facilitated diffusion require the use of energy?
Facilitated diffusion does not require the use of energy.
What is the movement of molecules from greater to lower?
This movement is called diffusion, where molecules move from an area of higher concentration to an area of lower concentration in order to achieve equilibrium. The process is driven by the random motion of molecules and does not require energy input.
What does NOT require the breakdown of ATP?
Passive transport mechanisms such as diffusion and osmosis do not require the breakdown of ATP, as they rely on the natural movement of molecules from an area of high concentration to low concentration. This process does not require energy input.
What is the movement of materials through a cell membrane?
Movement of substances into and out of cells include passive mechanisms that do not require cellular energy (diffusion, facilitated diffusion, osmosis, and filtration) and active mechanisms that use cellular energy (active transport, endocytosis,and exocytosis).
Does some diffusion require energy?
No. Diffusion is a natural occurrence of the net movement of substances from a region of higher concentration to a region of lower concentration (down the concentration gradient).
What is ATP used for in diffusion?
It's not. Diffusion does not require energy.
