Facilitated diffusion moves large molecules through?
Transport proteins and carrier proteins
Carrier proteins transport glucose into a muscle cell.?
carrier proteins transport glucose into a muscle cell
What is the process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins called?
The process by which molecules such as glucose are moved into cells along their concentration gradient with the help of membrane bound carrier proteins is called facilitated diffusion. Facilitated transport is passive and does not directly require chemical energy from ATP.
Some materials can move across the cell membrane against a concentration gradient by?
Large molecules such as glucose that cannot cross the phospholipid bilayer can still move across the membrane through transport proteins by active transport. Active transport uses energy to move molecules the bilayer.
What is the name of the process when glucose enters cells?
Glucose can move into cells by active or passive transport, in both cases membrane-spanning proteins are required. Active transport (SGLT) uses the concentration gradient of Sodium ions to move glucose against its concentration gradient. Passive transporters (GLUT) are only effective if the concentration of glucose in the cell is lower than outside the cell.
Why do cells need carriers proteins that transport glucose?
Large molecules, such as glucose, are not able to pass through the cell membrane. Therefore proteins are needed to transport them across.
Which protein is responsible for transport of glucose across cell membrane?
A family of proteins called GLUT carry glucose molecules across the cell membrane.

How do transport proteins work?
They are used in Facilitated Diffusion, helping to transport ions, macromolecules, and other substances incapable of entering a cell by themselves to cross through the plasma membrane of the cell.
How does the gloucose get into the cells?
There are glucose transport proteins. Since there are fewer glucose particles in the cell (when compared to the fluid outside of cells), it is passive transport, which occurs naturally. The transport protein is necessary for the glucose to pass through the cell membrane.
What can across the membrane with assistance?
large or polar molecules such as proteins, glucose or ions like Na+/K+
Why do oxygen molecules easily diffuse across a cell membrane while glucose molecules do not?
Oxygen molecules are small and nonpolar, which allows them to easily pass through the hydrophobic lipid bilayer of the cell membrane via simple diffusion. Glucose molecules, on the other hand, are larger and polar, making it more difficult for them to move through the nonpolar interior of the lipid bilayer. They require specific transport proteins or channels to facilitate their movement across the membrane.

How do glucose molecules cross a plasma membrane on the apical side of epithelial cells?
secondary active transport
