What else can I help you with?
Which molecules need facilitated diffusion. to move across the plasma?
The Glucose and the Amino Acids.
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called?
The process by which glucose can pass through a cell membrane by combining with special carrier molecules is called facilitated diffusion. In this process, carrier proteins aid in the movement of glucose across the membrane down its concentration gradient.
What substance is most commonly transported during facilitated diffusion?
Glucose is one of the most commonly transported substances during facilitated diffusion. Facilitated diffusion is the process by which specific molecules, like glucose, are transported across cell membranes with the help of carrier proteins. These carrier proteins facilitate the movement of molecules down their concentration gradient without requiring energy input.
Is Glucose and amino acids move in or out of a cell by . passive diffusion facilitated diffusion active transport endocytosis and exocytosis?
Glucose and amino acids typically move into cells via facilitated diffusion and active transport. Facilitated diffusion relies on specific transport proteins to help these molecules cross the cell membrane down their concentration gradient. In contrast, active transport requires energy to move them against their concentration gradient. Endocytosis and exocytosis are mechanisms for larger molecules or particles, not typically for glucose and amino acids.
What type of diffusion helps glucose enter the cell?
facilitated diffusion
How do glucose molecules cross a plasma membrane?
Facilitated Diffusion

These carrier proteins facilitate the movement of molecules down their concentration gradient without requiring energy input.
Does glucose enters a cell most rapidly by facilitated diffusion?
No, glucose enters a cell most rapidly through facilitated diffusion with the help of glucose transporters, such as GLUT proteins. Facilitated diffusion allows glucose to move down its concentration gradient into the cell without requiring energy.
How would you describe the process of facilitated diffusion of glucose through carrier proteins?
Facilitated diffusion of glucose through carrier proteins is a passive process where glucose molecules move across the cell membrane with the help of specific carrier proteins. These carrier proteins bind to glucose molecules on one side of the membrane and release them on the other side, allowing glucose to move from an area of high concentration to an area of low concentration without requiring energy input from the cell.
Glucose molecules cross the cell membrane by means of?
The answer is that glucose crosses a semi-permiable membrane by the process of facilitated diffusion. It cannot be by osmosis, because osmosis is the moving of only water from a concentration of high to low.

facilitated diffusion

Glucose and amino acids typically move into cells via facilitated diffusion and active transport.

In contrast, active transport requires energy to move them against their concentration gradient. Endocytosis and exocytosis are mechanisms for larger molecules or particles, not typically for glucose and amino acids.
How simple diffusion can be distinguished from facilitated diffusion?
Simple diffusion does not involve the use of transport proteins and relies on the concentration gradient of molecules for movement across the membrane. Facilitated diffusion, on the other hand, requires specific transport proteins to help facilitate the movement of molecules across the membrane, often against their concentration gradient.
A form of diffusion in which the molecules pass through a protein instead of between the phospholipids is called?
Glucose molecules are molecules that pass through a protein instead of between the phospholipids. This is because they are to big to diffuse through phospholipids.
A molecule such as glucose must use a protein channel to cross through a cell membrane?
This is correct. Glucose, being a large molecule, requires a protein channel called a glucose transporter to facilitate its passage through the cell membrane. Glucose transporters assist in transporting glucose molecules across the hydrophobic lipid bilayer of the cell membrane.
