What else can I help you with?
Does faciliated diffusion require energy?
Facilitated diffusion does not require energy because it relies on the use of carrier proteins to transport molecules across a cell membrane down their concentration gradient. These carrier proteins facilitate the movement of specific molecules such as glucose or ions without the need for ATP or energy input.
What kind of transport across a membrane does not require energy?
Passive transport does not require energy as it allows molecules to move across a membrane from an area of higher concentration to an area of lower concentration. Examples of passive transport include diffusion, osmosis, and facilitated diffusion.
How does kinetic energy affect diffusion rate?
The greater the collision rate, the greater the diffusion rate. As the molecules of the substance that is diffusing are more concentrated, the molecules collide more. As they diffuse and spread apart, there are less collisions and diffusion slows down.
Is kenetic energy used in passive transport?
No, passive transport does not use kinetic energy. Passive transport processes like osmosis, diffusion, and facilitated diffusion rely on the natural movement of molecules from an area of high concentration to an area of low concentration, without requiring additional energy input.
Does the particles need to contain kinetic energy for osmosis and diffusion?
Yes, particles need to contain kinetic energy in order for osmosis and diffusion to occur. This kinetic energy allows the particles to move and spread out from an area of high concentration to an area of low concentration through the process of osmosis and diffusion.
Does facilitated diffusion require the use of energy?
Facilitated diffusion does not require the use of energy.
Does the facilitated diffusion not require the cell to use energy?
It does not require the use of the cells energy.
Does diffusion diffusion use energy?
No, diffusion does not use energy because it is a form of passive transport. The definition (if anybody needs it) is the movement of molecules in a fluid or gas from a region of higher concentration to a region of lower concentration.
Does the facialited diffusion require the cell to use energy?
No, it does not require energy use from the cell.
Do cells gain and then use energy through facilitated diffusion?
Cells do not gain energy through facilitated diffusion. Facilitated diffusion is a passive process in which molecules move across the cell membrane from an area of higher concentration to lower concentration with the help of transport proteins, without the need for energy input. Cells use energy through other processes such as active transport and cellular respiration to maintain their functions.
What role does active transport play in diffusion?
active transport is kind of like diffusion, but unlike diffusion, it requires ATP(energy) and the molecule moves from low concentration to high concentration
Do unicellular organisms use energy for everything?
Unicellular organisms do not use energy for everything. For instance, diffusion across the cell membrane of the organism does not require the use of energy.
Which process requires no energy from the cell?
Passive transport. This process allows molecules to move across the cell membrane without the use of energy. It includes simple diffusion, facilitated diffusion, and osmosis.
What is diffusion in a cell?
Diffusion is an impromptu process in which cells allow certain substances to pass the plasma membrane, and not use any energy to do so.
What statements tells how facilitated diffusion differ from simple diffusion?
Particles move through cell membranes w/out the use of energy by cells.
Is the following sentence true or false Facilitated diffusion does not require the to use energy?
No. Facilitated diffusion is just diffusion through membrane proteins. But, it is still diffusion and the net movement of molecules is from high to low concentration and therefore does not require added energy. -H. C =)
Which transport does not require cell energy?
Diffusion is per definition a passive transport process.
