What is meant by passive transport of material across a membrane?
"Passive" mean that it does not require energy, therefore the passive transport of material across the membrane means that it can transport the material (cells or whatever) without the function of energy across the membrane.
What is the movement of materials across a membrane that requires energy input called?
Active transport requires energy and proteins to move the materials across the cell membrane. This is in contrast to osmosis, which doesn't require energy to move the material.
When an input of energy is required to move material through a cell membrane what transport takes place?
Active transport requires energy to move substances across a cell membrane against their gradient.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
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.
What kind of transport across membrane does not require energy?
Ghh
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.?
The process of moving materials across the cell membrane without the expenditure of energy is called passive transfer
What is the process of moving materials across membrane with energy?
active transport
What are the example of work?
ATP transports energy across a cells membrane
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.
What is the function of the carbohydrates that stick out if the plasma membrane?
The carbohydrates help identify chemical signals and define the characteristics of the cell.
What requires no energy to move things across the cell membrane?
