Why do solutes move across a lipid bilayer?
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.

What does the passive in passive transport mean?
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)
How does active transport differ from passive transport-?
Active transport requires energy while passive transport does not.
State how passive transport is powered?
Passive transport is powered by the natural kinetic energy of molecules, allowing them to move along their concentration gradient—from areas of higher concentration to areas of lower concentration—without the need for cellular energy (ATP). This process relies on mechanisms such as diffusion, facilitated diffusion, and osmosis. The driving force for passive transport is the tendency of substances to achieve equilibrium in concentration.
When does passive transport come to a stop?
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.
Why is the term 'equilibrium' used with passive but not active transport?
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.
What is an example of passive transport across a cell membrane?
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.
Is diffusion a form of passive transport?
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.
Why do solutes move across a lipid bilayer?
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.
The type of transport that requires no cellular 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.
Is transport proteins active transport or passive transport?
passive
Is passive equilibrium the same as equilibrium?
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.
