Facilitated diffusion, or diffusion through ion channels, is not a form of active transport. It is a spontaneous passive transport.
Both active transport and facilitated diffusion are methods of moving substances across cell membranes. Active transport requires energy input to move substances against their concentration gradient, while facilitated diffusion does not require energy and moves substances along their concentration gradient with the help of transport proteins.
No, diffusion and osmosis are passive transport processes, not active transport. Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration, while osmosis is the movement of water across a selectively permeable membrane. Active transport, on the other hand, requires energy and moves substances against their concentration gradient.
No, diffusion is not a form of active transport. Diffusion is a passive process where molecules or ions move from an area of high concentration to an area of low concentration, driven by the concentration gradient. Active transport, on the other hand, requires energy expenditure to move molecules or ions against their concentration gradient.
Osmosis and simple diffusion are not sufficient for the transport of all substances due to their nature. They only have the ability to transport substances which can pass through the cell membrane.
Facilitated diffusion involves the movement of molecules across a cell membrane with the help of a specific protein carrier, while active transport uses energy in the form of ATP to transport molecules against their concentration gradient. Facilitated diffusion does not require energy input, whereas active transport does.

Most molecules cross the cell membrane through passive diffusion, facilitated diffusion, or active transport. Passive diffusion relies on the concentration gradient, facilitated diffusion involves the use of protein channels or carriers, and active transport requires energy to move molecules against their concentration gradient.
Diffusion is an example of passive transport, like osmosis(the diffusion of water through a membrane).
Charged particles move across membranes through the process of facilitated diffusion or active transport. Facilitated diffusion involves the movement of particles through protein channels, while active transport requires energy to move particles against their concentration gradient.
Osmosis, diffusion, facilitated diffusion, active transport
Three ways molecules move through a semipermeable membrane are simple diffusion, facilitated diffusion, and active transport. In simple diffusion, molecules move from an area of high concentration to low concentration without the need for energy. Facilitated diffusion involves the movement of molecules across the membrane with the help of protein channels or carriers. Active transport requires energy and moves molecules against their concentration gradient.
No, diffusion is where particles flow in order to be equal, whereas active transport uses ATP to move them through a cell membrane.
Substances can move in and out of a cell in several ways. Diffusion is when a substance will distribute itself in or out of a cell until the distribution on both sides of the cell is balanced. Active transport is when a cell transports a substance across the cell membrane that would not normally be able to pass through. Osmosis is the movement of water from areas with few dissolved dissolved substances to areas with high dissolved substances.
Active transport uses energy while diffusion does not
Yes, when channels are specific for the structures of individual molecules it is active transport. Active transport cannot occur if the energy they are moving is not of the same type, like glucose cannot move calcium.
passive or active transport. Passive transport does not require energy input and includes processes like diffusion and facilitated diffusion. Active transport requires energy input and includes processes like primary active transport and secondary active transport.
