Active transport.
Active transport.
It is a type of active transportation.So energy is needed.
Active transport.
Passive transportation of substances across the cell membrane is called passive diffusion. It does not require energy input from the cell and relies on the concentration gradient to move molecules from high concentration to low concentration.
Active transportation is the material that across plasma membrane. This makes it flow one way.
requires the input of energy and a carrier protein to move nutrients across a concentration gradient
Idoes active transport always require transport proteins during the process
Facilitated diffusion across a biological membrane requires the presence of specific protein channels or carriers to assist in the movement of molecules from an area of high concentration to an area of low concentration. The process does not require energy input from the cell and relies on the concentration gradient to drive the movement of molecules.
Active transportation
Energy-requiring process by which substances move across the plasma membrane against a concentration gradient.
