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 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.
Active transport always requires transport proteins during the process?
false
What ways of moving molecules across a membrane requires energy?

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.

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.
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.
What are the four types of proteins found in the cell membrane?
Actually, bilipid "heads" form the layers of the membrane, but there are carrier proteins that transport objects into and out of the cells. These carrier proteins use either active or passive transport to get objects across the membrane. Active transport uses energy, while passive transport doesn't need to use energy to get items across. Hope this helps!!!
