What else can I help you with?
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
How does diffusion from active transport?
Active transport expends energy, unlike osmosis and diffusion. Active transport is a way to move substances against concentration gradients in the cell membrane, so they need more energy to do so.
What is used to move a substance through a membrane in active transport?
Electrochemical gradient is used to move substances through a membrane in active transport.
What do materials move from in active transport?
They move from the environment into the cell.
What is the purpose of active transport?
Active transport expends energy to move substances against a concentration gradient.
Is active transport able to move molecules against the concentration gradient?
Yes, active transport is able to move molecules against the concentration gradient.
What type of transport requires energy to move molecule?
Active transport requires energy to move a molecule.
What is it called when materials move from lower to higher concentration?
Specifically Diffusion, but it is also active transport
How does active transport differ from diffusion?
Active transport expends energy, unlike osmosis and diffusion. Active transport is a way to move substances against concentration gradients in the cell membrane, so they need more energy to do so.
What ways can cells move things by active transport?
. One method is that transport proteins in the cell membrane "pick up" molecules from outside the cell and carry them in, while using energy in the process. A second method is that the cell membrane surrounds a particle and takes it in.
What they call the process for a molecule to move from an area of low concentration to high concentration?
Active transport
What is the definition of active transport?
active transport is an energy reqiuring process in which transport proteins bind with particles and move them through a cell membrane
