What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What ways of moving molecules across a membrane requires energy?
Active Transport.
What is net movement of substances across plasma membrane without additional energy?
Diffusion. With the need of energy, it would be called active transport.
What process drives molecules across a membrane against a concentration gradient?
Active Transport.
A type of passive transport across a cell membrane that requires special carriers is?
Active transport
The use of energy to move substances across a cell membrane describes?
Active Transport
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.
Active transport requires what?
Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.
What is it called when molecules uses energy to move across a semipermeable membrane?
Active transport
What is the name of the membrane that allows the movement of water and substances to move through the process of active transport and passive transport?
The name of the membrane that allows movement of water and substances through the process of active and passive transport is semipermeable 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.
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.
Which processes are active transport of substances in and out of the cell?
cell membrane
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 the movement of chemical substances usually across the cell membrane againts a concentration gradient requires cells to energy?
active transport
What energy from the hydrolysis of ATP is used to drive substances across the membrane against their own concentration gradients?
primary active transport
How is passive transport different then active transport?
An example of passive transport would be the process of osmosis (water diffusing between a membrane-- from an area of high concentration to an area of low concentration). It is known as passive transport because no energy is needed in order to move the water across the membrane. When no energy is needed to move the substance it is considered passive transport. On the other hand, when energy IS needed to transport molecules or substances across a membrane it is referred to as active transport. An example of this would be a calcium pump located in the lipid bilayer of a plasma membrane which can transport potassium (K+) ions across it. Energy is needed in order to move those potassium ions across the membrane, and therefore is referred to as active transport.
