Solutes can move across a lipid bilayer through passive diffusion, facilitated diffusion, or active transport. Passive diffusion occurs when solutes move down their concentration gradient, facilitated diffusion involves the use of transport proteins, and active transport requires energy to move solutes against their concentration gradient.

Passive Transport is the movement of molecules down a concentration gradient from a region of high concentration to a region of low concentration until equilibrium is reached. Some examples are diffusion and osmosis. Basically, it's a movement of molecules across a membrane that doesn't require energy (ATP)
Active transport requires energy while passive transport does not.
Passive diffusion occurs because molecules move from an area of higher concentration to an area of lower concentration, in order to reach equilibrium. This process does not require the input of energy.
Passive transport does not come to a stop as long as there is a concentration gradient. Once equilibrium is reached and there is no longer a difference in concentration on either side of the membrane, passive transport will slow down significantly but may continue at a very slow pace.
The term "equilibrium" is used with passive transport because it describes a state where there is no net movement of molecules across a membrane due to equal concentration on both sides. In active transport, energy is used to move molecules against their concentration gradient, so equilibrium is not reached as the process continues to pump molecules in or out of the cell.
Osmosis is a type of passive transport. It is specialized diffusion. It can occur through the membrane itself. Or through an aquaporin channel protein. Other forms of passive transport include: simple diffusion and facilitated (uses channel protein) diffusion.
Solutes can move across a lipid bilayer through passive diffusion, facilitated diffusion, or active transport. Passive diffusion occurs when solutes move down their concentration gradient, facilitated diffusion involves the use of transport proteins, and active transport requires energy to move solutes against their concentration gradient.
when diffusion occurs it is because the substance is trying to reach equilibrium, where everything is equally spread out on both sides of a cell membrane. things naturally want to be at equilibrium in nature so this happens automatically and doesn't require any energy. and that is the definition of passive transport transportation of a substance through a cell membrane that doesn't require any energy.
Passive transport requires no cellular energy as it relies on the movement of molecules down their concentration gradient, such as diffusion and osmosis. These processes occur spontaneously to maintain equilibrium within the cell.
passive
No, passive equilibrium refers to a state where a system remains at rest or in a fixed position without external energy input. Equilibrium, on the other hand, is a state in which opposing forces or influences are balanced. Passive equilibrium can be a type of equilibrium but not all equilibriums are passive.
