What else can I help you with?
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
Is passive tansport the answer to particles moving across a cell membrane without using energy?
Yes, passive transport is the process by which particles move across a cell membrane without the input of energy. This can occur through processes like diffusion and osmosis, where particles move down their concentration gradient to reach equilibrium.
What uses a protein to move a molecule across a membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
How do you use passive transport in a sentence?
Passive transport is a process in cells where substances move across the cell membrane without requiring energy input. An example of passive transport is the movement of oxygen and carbon dioxide across the cell membrane through simple diffusion.
Which process is characterized by the movement of particles from an area of high concentration to an area of low concentration across the plasma membrane without the use of energy?
passive transport (e2020 answer)
What used a protein to move a molecule across a cell membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
When sugars pass across a membrane without the use of energy?
Passive transport.
Diffusion and osmosis are forms of what?
Diffusion and osmosis are forms of passive transport, which is the movement of particles across a membrane without requiring energy input from the cell.
Why is energy needed to move the particles across the plasma membrane?
Energy is only necessary for diffusion if the particles are being moved across the membrane against the gradient. ATP is necessary for this active transport as particles are moved from low concentrations to higher concentrations across the membrane. This is because passive transport, which does not use energy, only works to move particles down their concentration gradient. Ex. Such active transport is used in neuron cells to have a different charge inside and outside of the cell so that it can relay electric signals.
What is the movement called when a cell does not use energy to move particles across the cell's membrane?
It is called passive diffusion.
What is the movement called when a call does not use energy to move particles across the cells membrane?
It is called passive diffusion.
Which activity can occur without use of energy?
Movement of water across the cell membrane
