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.

How does the movement of materials across the cell membrane relate to an organism's survival?
A cell has to have some thing moving across it or the cell will most certanly die.
What is the movement of chemical substances usually across the cell membrane againts a concentration gradient requires cells to energy?
active transport
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
The movement of substances across the cell membrane that requires the cell to use energy?
It's called active transport. When talking about the cell, it is usually bigger substances that use passages in the cell membrane to access the inner part of the cell, and they need energy to get there. The opposite; passive transport or diffusion, is the movement of dissolved materials through a cell membrane without the use of cellular energy. THis happens with smaller substances.
The resistance to an ion's movement across a membrane is determined by?
ion channels within the membrane
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
How is passive transport from active transport?
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
How is the movement of materials across the cell membrane related to the survival of the organism?
its your mama :p
What is the movement of materials across a cell membrane without using energy?
This type of movement is called simple diffusion.
What is the function of active transport moving small molecules and ions across cell membrane?
the movement of materials against a concentration difference is known as active transport. Active transport requires energy.
How is active transportation different from passive transportation?
The movement of materials across the cell membrane without using cellular energy is called passive transport. The movement of materials against a concentration difference is known as active transport. Active transport requires energy.
The movement of water across a membrane is trem?
The movement of water across a membrane is called osmosis.
How does the movement of materials across the cell membrane relate to an organism's survival?
A cell has to have some thing moving across it or the cell will most certanly die.
How do fluid materials transport through membrane osmosis osmosis?
Osmosis is the movement of water across a selectively permeable membrane from where it is in high concentration to where it is in low concentration.
What are ways materials can move in and out of cells?
Most movement of materials is categorized as diffusion, meaning that materials move from areas of high concentration (i.e., a crowded room) to low concentration (an adjoining, empty room).Some materials move in the opposite pattern, called active transport. This requires ATP (energy).Finally, the movement of water across a cell membrane is called osmosis.Keep in mind, the cell membrane controls the movement of all substances. It is selectively permeable, which means that it only allows certain things in and out.
What is the movement of chemical substances usually across the cell membrane againts a concentration gradient requires cells to energy?
active transport
What movement do ion channels aid?
the movement of ions across a cell membrane.
