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.

How do diffusion osmosis facilitated diffusion and active transport diffusion differ?
Diffusion is the movement of particles from an area of high concentration to low concentration. Osmosis is the diffusion of water across a selectively permeable membrane. Facilitated diffusion involves the use of transport proteins to help molecules move across the cell membrane. Active transport requires energy to move molecules against their concentration gradient, often utilizing protein pumps.
How does diffusion differ from facilitated diffusion?
Diffusion is the movement of molecules from an area of high concentration to low concentration without the need for a protein carrier. Facilitated diffusion also moves molecules from high to low concentration but requires a specific protein carrier to assist in the process.
Is Lysol an acid?
Lysol is a disinfectant product that contains various chemicals for cleaning and germ-killing purposes, but it is not considered an acid. It typically has a pH level that is neutral or slightly alkaline.
What are two main kind of cetaceans how do they differ?
dolphins and whales
How does human language differ from animal communication?
"We speak english"
How can active transport differ from passive transport?
Active transport requires energy input to move molecules against their concentration gradient, while passive transport does not require energy and moves molecules along their concentration gradient. Active transport usually involves the use of transport proteins, such as pumps or carriers, while passive transport relies on diffusion or facilitated diffusion.
How does active transport differ from diffusion?
Active transport requires energy to move molecules across a cell membrane against their concentration gradient, while diffusion occurs spontaneously and does not require energy. Active transport is selective and can move molecules against their concentration gradient, while diffusion moves molecules from an area of high concentration to an area of low concentration.
How do the roles of protein molecules in diffusion differ and active transport?
Proteins are involved in passive diffusion as channels or carriers that facilitate the movement of molecules across a membrane based on concentration gradients. In active transport, proteins use energy to actively transport molecules against their concentration gradient, requiring ATP to drive the process.
How does active transport differ from passive transport-?
Active transport requires energy while passive transport does not.
How do facilitated diffusion and active transport compare and contrast in terms of their mechanisms of transport across the cell membrane?
Facilitated diffusion and active transport are both ways that substances move across the cell membrane, but they differ in their mechanisms. Facilitated diffusion uses protein channels to help substances passively move from areas of high concentration to low concentration, while active transport requires energy to move substances against their concentration gradient using protein pumps.
How does active transport differ from osmosis?

Compare and contrast diffusion and facilitated diffusion?
Diffusion is the process by which particles move from an area of high concentration to an area of low concentration without the need for a transport protein. Facilitated diffusion is similar to diffusion but requires the assistance of specific transport proteins to move particles across a membrane. Both processes help maintain equilibrium within a cell or between cells and their environment.
How do faciliated diffusion and active transport differ?
Facilitated diffusion is a passive process where molecules move across a membrane with the help of transport proteins, following their concentration gradient. Active transport requires energy input (ATP) to move molecules against their concentration gradient with the help of transport proteins.
How active transport is differ with Diffusion and Osmosis?
Active transport requires energy input to move molecules against their concentration gradient, from low to high concentration. Diffusion is the passive movement of molecules from high to low concentration, while osmosis is the passive movement of water across a selectively permeable membrane driven by differences in solute concentration.
How does active transport differ from the process of diffusion across a membrane?
Active transport requires energy and moves molecules against their concentration gradient, from an area of low concentration to high concentration. Diffusion, on the other hand, is a passive process where molecules move from an area of high concentration to low concentration without requiring energy.
How does facilitated diffusion contrast with active transport in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion and active transport are both ways that molecules can move across the cell membrane, but they differ in their mechanisms. Facilitated diffusion uses protein channels or carriers to help molecules move from an area of high concentration to low concentration without requiring energy. Active transport, on the other hand, uses energy to move molecules against their concentration gradient, often with the help of protein pumps.
