What is carrier-assisted transport?
Carrier-assisted transport is a mechanism in which a carrier molecule assists in the movement of a substance across a biological membrane. The carrier molecule can bind to the substance and facilitate its transport across the membrane. This process is typically passive and does not require energy input from the cell.
What process require ATP energy to transport materials across a selectively premeable membrane into the cell?
active transport
If a substance is able to diffuse across a membrane then the membrane is said to be what?
selectively permeable
What is the membrane said to be if a substance is able to diffuse across a membrane?
selectively permeable
Does the process of endo and exocytosis require energy?
Yes, both endocytosis and exocytosis require energy in the form of ATP to transport molecules across the 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.
Does passive transport require ATP for the movement of molecules across the cell membrane?
No, passive transport does not require ATP for the movement of molecules across the cell membrane.
If a substance is unable to diffuse across a membrane we say the membrane is?
osmotically active
What is the process that utilizes a carrier to move materials across the plasma membrane in the direction of the concentration gradient that does not use ATP?
Active Transport
Movement of a substance across a cell membrane using chemical energy occurs during?
Active transport is the movement of a substance across a cell membrane using chemical energy. This process requires the use of a carrier protein and ATP to transport molecules against their concentration gradient.
