Passive transport moves molecules from a high to low concentration gradient.
Passive transport moves with the concentration gradient.
No, passive transport does not move substances against the concentration gradient. It moves substances from an area of high concentration to an area of low concentration without requiring energy input.
Yes, passive transport moves substances with the concentration gradient.
Active transport and passive transport are two different processes by which substances move across a cell membrane. Passive transport does not require energy and relies on the natural movement of molecules from an area of high concentration to an area of low concentration. Active transport, on the other hand, requires energy in the form of ATP to move molecules against their concentration gradient, from an area of low concentration to an area of high concentration. This difference in energy requirements is what distinguishes active transport from passive transport.
Molecules move by passive transport down their concentration gradient, from an area of higher concentration to an area of lower concentration, without the input of energy. This can occur through simple diffusion, facilitated diffusion, or osmosis, depending on the properties of the molecules and the cellular environment.
Passive transport moves down the concentration gradient, from an area of higher concentration to an area of lower concentration.
Active transport requires energy; passive transport does not.
passive transport does not require energy eg. diffusion and osmosis. Therefore, osmosis is a passive transport. Active transport requires energy eg. a molecule going from a low concentration from a high concentration.
Active transport requires energy to move molecules against their concentration gradient while passive transport does not require energy and moves molecules from high to low concentration. Active transport is selective and can transport specific molecules, while passive transport is nonselective and moves molecules based on their concentration gradient.
Energy is not required for passive transport to occur. Passive transport processes such as diffusion and osmosis rely on the inherent kinetic energy of molecules to move from an area of high concentration to an area of low concentration without the need for external energy input.
Two examples of passive transport are simple diffusion, where molecules move across a membrane from an area of high concentration to low concentration, and facilitated diffusion, where molecules move across a membrane with the help of specific transport proteins.
Absolutely, in order for passive transport to occur, the concentration on one side of the membrane must be larger than the concentration on the other side of the membrane. The molecules move from higher to lower concentration.
