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.
The use of energy to move substances across a cell membrane describes?
Active Transport
What is it called when the movement of materials through a cell membrane without using the cells energy?
Passive transport does not use energy to pass through a cell membrane. active transport uses energy to pass through a cell membrane.
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.
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.
What is it called when substances move past the membrane without using energy?
Passive transport is when substances move past the membrane without using any energy.
What is it called when substances move past the membrane without using any energy?
Passive transport is when substances move past the membrane without using any energy.
What are 2 ways that substances across the cell membrane without using energy?
simple diffusion, facilitated diffusion, and osmosis (water)
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 is net movement of substances across plasma membrane without additional energy?
Diffusion. With the need of energy, it would be called active transport.
Does active transport get substances across a cell membrane?
Transport proteins
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.
The use of energy to move substances across a cell membrane describes?
Active Transport
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.
What is the movement of substances through a cell membrane without the use of cell energy?
passive transport
What moves materials in a cell membrane without using energy?
Passive transport is the process in which dissolved materials move across a cell membrane without using a cell's energy.
