What is meant by passive transport of material across a membrane?
"Passive" mean that it does not require energy, therefore the passive transport of material across the membrane means that it can transport the material (cells or whatever) without the function of energy across the membrane.
What motion of particles across a membrane requires energy?
Movement across a membrane that does require energy is called active transport.
How is energy made available to the cell to move large starch molecules across the membrane through the process of endocystosis?
Energy for endocytosis, the process by which cells move large molecules like starch across the membrane, is primarily derived from ATP (adenosine triphosphate). During endocytosis, the cell membrane invaginates to engulf extracellular material, forming a vesicle that brings the material into the cell. This process requires energy to rearrange the cytoskeletal components and facilitate membrane fusion. Consequently, ATP provides the necessary energy for these cellular activities, enabling the transport of large molecules.
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.
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.
What uses a protein to move a molecule across a membrane without energy?
Facilitated diffusion uses proteins to move a molecule across the cell membrane without energy.
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.
When an input of energy is required to move material through a cell membrane what transport takes place?
Active transport takes place when an input of energy is required to move material through a cell membrane. This process uses energy to move molecules against their concentration gradient, often utilizing specific carrier proteins to facilitate the transport.
What kind of transport across membrane does not require energy?
Ghh
What is the process of moving materials across membrane with energy?
