What else can I help you with?
Which process requires energy to bring molecules across the cell membrane?
Active transport requires energy to move molecules across the cell membrane against their concentration gradient. This process is carried out by specific proteins called pumps that utilize cellular energy in the form of ATP to transport molecules.
When a cell expands energy to move molecules or ions across membrane the process is known as?
Active transport. This process requires energy, usually in the form of ATP, to move molecules or ions against their concentration gradient across a cell 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 motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
What does facilitated diffusion requires?
Facilitated diffusion requires the presence of specific carrier proteins embedded in the cell membrane to help transport molecules across the membrane. These carrier proteins assist in the movement of molecules down their concentration gradient without requiring energy input from the cell.
Which process requires energy to bring molecules across the cell membrane?
Active transport requires energy to move molecules across the cell membrane against their concentration gradient. This process is carried out by specific proteins called pumps that utilize cellular energy in the form of ATP to transport molecules.
What type of transport requires energy move a molecule?
Active transport requires energy to move a molecule.
What process requires energy from the cell?
facilitated diffusion
When a cell expands energy to move molecules or ions across membrane the process is known as?
Active transport. This process requires energy, usually in the form of ATP, to move molecules or ions against their concentration gradient across a cell membrane.
Does facilitated diffusion require energy for the movement of molecules across the cell membrane?
No, facilitated diffusion does not require energy for the movement of molecules across the cell membrane.
Does facilitated diffusion require energy for the transportation of molecules across the cell membrane?
Facilitated diffusion does not require energy for the transportation of molecules across the cell membrane.
Does facilitated diffusion require energy to transport molecules across the cell membrane?
Facilitated diffusion does not require energy to transport molecules across the cell membrane.
How is active transport different from facilitated diffusion in terms of the energy requirement for moving molecules across the cell membrane?
Active transport requires energy in the form of ATP to move molecules across the cell membrane against their concentration gradient, while facilitated diffusion does not require energy and moves molecules along their concentration gradient.
What is the movement of materials across a membrane that requires energy input called?
Active transport is the movement of materials across a membrane that requires energy input, typically in the form of ATP. This process allows cells to move molecules against their concentration gradient, ensuring the proper balance of ions and molecules inside and outside the cell.
Does facilitated transport require energy for the movement of molecules across the cell membrane?
Yes, facilitated transport does require energy for the movement of molecules across the cell membrane.
Active transport is the process of what?
Active transport is the process by which a cell uses energy to move molecules or ions across a cell membrane against their concentration gradient. This process requires the use of ATP energy to pump substances from an area of low concentration to an area of high concentration.
Is diffusion of molecules across the cell membrane the most complex type of active?
Diffusion of molecules across the cell membrane is actually a passive process, not active. Active transport, which requires energy in the form of ATP, is a more complex process as it moves molecules against their concentration gradient.
