Which row in the chart below best describes the active transport of molecule X through a cell membrane?
Low concentration to high concentration; ATP is used
What else can I help you with?
What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.
What is it called a molecule moves across a membrane through a protein channel without using energy?
Passive Transport
What is it called when a molecule moves across a membrane through a protein channel without using energy '?
Passive Transport
What is the molecule that requires energy to pass through the cell membrane?
The molecule that requires energy to pass through the cell membrane is typically an ion or a large polar molecule, such as glucose, which moves against its concentration gradient. This process is known as active transport and involves the use of ATP or other energy sources to facilitate the movement of these substances through specific transport proteins in the membrane. Examples include sodium-potassium pumps and glucose transporters.
A special molecule that uses energy to push molecules through a membrane of a cell is called?
The special molecule is called ATP, which stands for adenosine triphosphate. ATP provides the necessary energy to power transport proteins in the cell membrane to move molecules across it.
What happens if a molecule is too large to go through a membrane?
The molecule will be transported across the membrane by way of a transport protein or protein channel.
What type of molecule embedded in the cell membrance allows larger molecule to pass through the membrance by active transport?
Transport proteins allow the active transport of large molecules through the cellular membrane.
What is the process by which substances are moved through the cell membrane by a carrier molecule?
facilitated diffusion or active transport

Which term describes the movement of water molecule in and out of the cell?
The movement of water through a semipermeable membrane is called osmosis.
