What ways of moving molecules across a membrane requires energy?
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
What requires the use of energy and help of transport proteins to move a molecule across a cell membrane?
Facilitated diffusion
What requires the use of energy and the help of transport proteins to move a molecule across the cell membrane?
Facilitated diffusion
Molecules move from an area of low concentration to an area of high concentration during?
Active transport. This process requires energy to move molecules against their concentration gradient, typically through the use of transport proteins in the cell membrane.
What requires the use of energy and the help of transport proteins to move a molecule across a cell membrane apex?
The process that requires energy and the assistance of transport proteins to move a molecule across a cell membrane is called active transport. This mechanism allows cells to move substances against their concentration gradient, from areas of lower concentration to areas of higher concentration. Transport proteins, such as pumps, facilitate this movement by binding to the specific molecules and utilizing ATP or another energy source to drive the process. Examples include the sodium-potassium pump, which maintains essential ion gradients in cells.
Active transport always requires transport proteins during the process?
false
What ways of moving molecules across a membrane requires energy?
Active transport requires energy to move molecules across a membrane against their concentration gradient. This process is facilitated by specific carrier proteins embedded in the membrane that use energy, usually in the form of ATP, to transport molecules.
Does osmosis involve the use of proteins in its process?
Yes, osmosis does not involve the use of proteins in its process. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. This process does not require the use of proteins.

Active transport. This process requires energy to move molecules against their concentration gradient, typically through the use of transport proteins in the cell membrane.
What does active transport requires?
Active transport requires the use of energy, usually in the form of ATP, to move molecules or ions across a cell membrane against their concentration gradient. This process is essential for maintaining cell functions and often involves specific transport proteins or pumps.
Does osmosis involve the use of transport proteins?
No, osmosis does not involve the use of transport proteins. Osmosis is the movement of water molecules across a selectively permeable membrane from an area of higher concentration to an area of lower concentration. Transport proteins are not involved in this process.
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.
Which type of membrane transport process uses ATP as a source of energy?
Active transport processes use ATP as a source of energy to move molecules against their concentration gradient across a cell membrane. This process requires specific transport proteins, such as ion pumps, to actively transport molecules across the membrane.
How simple diffusion can be distinguished from facilitated diffusion?
Simple diffusion does not involve the use of transport proteins and relies on the concentration gradient of molecules for movement across the membrane. Facilitated diffusion, on the other hand, requires specific transport proteins to help facilitate the movement of molecules across the membrane, often against their concentration gradient.
