DEAR FRIEND,
FACILITATED DIFFUSION :
Facilitated diffusion?(also known as?facilitated transport?or?passive-mediated transport) is the process of spontaneous?passive transport?(as opposed to?active transport) of molecules or ions across a?biological membrane?via specific?transmembrane integrel proteins. Being passive, facilitated transport does not directly require chemical energy from ATP hydrolysis in the transport step itself; rather, molecules and ions move down their concentration gradient reflecting its diffusive nature.
FACTORS AFFECTING FACILITATED DIFFUSION ARE :
1). TEMPERATURE.
2). CONCENTRATION.
3). DIFFUSION DISTANCE.
4). SIZE OF THE MOLECULE.
HOPE YOU UNDERSTAND THIS ANSWER.
THANK YOU.
