WebAug 20, 2024 · Facilitated diffusion is a type of passive transport that allows substances to cross membranes with the assistance of special transport proteins. Some molecules and ions such as glucose, sodium ions, and chloride ions are unable to pass through the phospholipid bilayer of cell membranes. WebSep 12, 2024 · Active transport requires energy for the process by transporting molecules against a concentration or electrochemical gradient. Active transport is an energy-driven process where membrane proteins transport molecules across cells, mainly classified as either primary or secondary, based on how energy is coupled to fuel these mechanisms. f4 thailand 6 rész
