No, facilitated diffusion is not an organelle; it is a biological process. This process involves the movement of molecules across a cell membrane through specific transport proteins, allowing substances to pass without the expenditure of energy. It occurs in various cell types and is essential for transporting polar and charged molecules that cannot easily cross the lipid bilayer. Organelles, on the other hand, are specialized structures within a cell that perform specific functions.

What is diffusion a natural movement of molecules from?

in the normal diffusion the substance move from the area of greater concentration to that of lower concentration. .... but i never know what do we mean be "faciliated" plz specify


What organelle similar to diffusion?

The organelle similar to diffusion is the cell membrane, which regulates the movement of substances in and out of the cell. It allows small molecules and ions to pass through via simple diffusion, balancing concentrations inside and outside the cell. Additionally, the membrane contains proteins that facilitate facilitated diffusion, helping larger or polar molecules cross more efficiently. Thus, the cell membrane plays a crucial role in maintaining homeostasis through diffusion-like processes.


What cell organelle controls entry into cell?

The cell organelle that controls entry into the cell is the cell membrane. It acts as a selective barrier, allowing only specific molecules to enter and exit the cell through processes like diffusion, facilitated diffusion, active transport, and endocytosis.


What is one example of a substance using faciliated transport?

fatty acids membranes


What requires energy diffusion fcilitated diffusion osmosis active transport?

Active transport requires energy, typically in the form of ATP, to move molecules across a cell membrane against their concentration gradient. Facilitated diffusion, while it still uses membrane proteins to transport molecules, does not require energy as it follows the concentration gradient. Osmosis is the movement of water across a semipermeable membrane from an area of low solute concentration to an area of high solute concentration, also not requiring energy.

By what process are bacteria brought into a cell?

Bacteria can enter a cell through a process called phagocytosis, where the cell engulfs the bacteria using its cell membrane. Alternatively, some bacteria can invade cells by injecting proteins that manipulate the host cell machinery to gain entry.


How is faciliated transport similar to simple diffusion?

Facilitated and simple diffusion both transport solutes along a concentration gradient and neither processes require any ATP expenditure.


Does faciliated diffusion require energy?

Facilitated diffusion does not require energy because it relies on the use of carrier proteins to transport molecules across a cell membrane down their concentration gradient. These carrier proteins facilitate the movement of specific molecules such as glucose or ions without the need for ATP or energy input.


What type of transport is faciliated diffusion?

Neither of these require energy. Diffusion occurs naturally when a higher concentration of a substance exists on one side of a membrane than the other; molecules will enter into the area of lesser concentration until there is an equilibrium on both sides. Active transport requires the energy of the cell.

Which organelle is involved in osmosis and diffusion?

The cell membrane, also known as the plasma membrane, is the organelle involved in osmosis and diffusion. It acts as a barrier that regulates the flow of molecules in and out of the cell, allowing for the passive movement of substances such as water and solutes through the process of osmosis and diffusion.


How does faciliated diffusion differ from simple diffusion?

Facilitated diffusion needs some sort of help. Often it would be a protein. Simple diffusion doesn't. If you spill something smelly on the floor in the kitchen, you will smell it all through the house. It will spread by simple diffusion.


How does the structure of the plasma membrane determines the route taken by vitamin C and vitamin D?

Vitamin C is water soluable so the only way it can be transported is by faciliated difficusion using a channel protein. Channel proteins allow polar, watersoluable substances and ions to pass across the cell membrane using faciliated diffusion. Vitamin D is lipid soluble therefore it can pass through using simple diffusion because the phospholipid bilayer lets it pass through down its concentration gradient.

What organelle is responsible for allowing cells to perform diffusion?

The cell membrane (phospholipid bilayer) regulates what comes and goes in cells.


What process permits absorption of glucose into cells?

The process that permits absorption of glucose into cells is called facilitated diffusion. Glucose is transported across cell membranes with the help of glucose transport proteins, such as GLUT-1 and GLUT-4. These proteins allow glucose to move down its concentration gradient and into the cells where it can be used for energy production.
