Facilitated diffusion is a passive process that uses carrier proteins to transport molecules across the cell membrane along their concentration gradient, while active transport is an energy-dependent process that uses ATP to move molecules against their concentration gradient through protein pumps.
What else can I help you with?
What types of transport mechanisms through the cell membrane are passive?
diffusion, facilitated diffusion, and osmosis
How are facilitated diffusion and active transport different in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion uses transport proteins to move molecules across the cell membrane with the concentration gradient, while active transport requires energy to move molecules against the concentration gradient.
What are the similarities between facilitated diffusion and active transport in terms of their mechanisms of transporting molecules across the cell membrane?
Facilitated diffusion and active transport are both methods of transporting molecules across the cell membrane. They both involve the use of specific carrier proteins to facilitate the movement of molecules. However, the key difference is that facilitated diffusion does not require energy input from the cell, while active transport does require energy in the form of ATP to move molecules against their concentration gradient.
What are the similarities between active transport and facilitated diffusion in terms of their mechanisms of transporting molecules across the cell membrane?
Both active transport and facilitated diffusion are mechanisms that transport molecules across the cell membrane. They both involve the movement of molecules from an area of higher concentration to an area of lower concentration. However, active transport requires energy input from the cell to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules pass through the membrane.
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.

What macromolecule is involved in facilitated diffusion?
Facilitated diffusion involves the transport of molecules across the cell membrane with the help of transport proteins. These transport proteins are typically made up of proteins, which are macromolecules. Therefore, macromolecules involved in facilitated diffusion are proteins.
What does not require energy from the cell?
I believe it is facilitated diffusionendocytosis
What is a protein moves molecules across a membrane?
Facilitated diffusion moves molecules through cell membranes passively.
What are five transport mechanism where by metabolites nutrient or ions cross the cell membrane?
There are many forms of membrane and cell transport. These are the basic transport mechanisms in a prokaryotic animal cell. Facilitated Diffusion Osmosis Diffusion Exocytosis (this takes two forms; phagocytosis and pinocytosis depending on whether the cell is "eating" or "drinking") Endocytosis Carrier Molecules/Channel Proteins
How does passive diffusion differ from facilitated diffusion in terms of their mechanisms of transport?
Passive diffusion and facilitated diffusion both involve the movement of molecules across a cell membrane, but they differ in their mechanisms of transport. Passive diffusion does not require the assistance of transport proteins and relies on the natural movement of molecules from an area of high concentration to an area of low concentration. Facilitated diffusion, on the other hand, involves the use of specific transport proteins to help molecules move across the membrane, typically from an area of high concentration to an area of low concentration. In summary, passive diffusion is a simple process driven by concentration gradients, while facilitated diffusion involves the assistance of transport proteins for more efficient movement of molecules.
What are the key differences between active transport and facilitated diffusion in terms of their mechanisms of movement across cell membranes?
Active transport requires energy input to move molecules against their concentration gradient, while facilitated diffusion does not require energy and relies on carrier proteins to help molecules move down their concentration gradient across the cell membrane.
