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.

Large molecules such as glucose can not cross the lipid bi layer can still move across the membrane with a concentration gradient by water. Carbon dioxide and oxygen will move large molecules across the gradient as well.

The transport of a substance across the cell membrane against its concentration gradient is called active transport.


What is the transport of materials against a concentration gradient called?

The process of moving materials against a concentration gradient is called active transport. Active transport generally uses a protein pump to move molecules from an area of low concentration to an area of high concentration; in order to perform an active transport, the cell must use some of its energy to initiate the reaction.

What moves solutes against concentration gradient?

The processes that can move a solute against its concentration gradient are active transport. All cells are enclosed by a plasma membrane that is similar in structure and function.


How does difference in concentration relate to movement of substances across the membrane?

the concentration gradient will help to bring stuff into the cell and to move stuff out. Osmosis likes to move with the concentration gradient. Moving with a concentration gradient is passive transport and moving against it is active transport


What is a characteristic that diffusion and active transport have in common and both process?

Both involve the transport of materials across the cell membrane. Active transport goes against the concentration gradient and requires ATP. Diffusion goes with the concentration gradient, or from high to low concentration, and does not require ATP. ATP is the standard unit of energy in cells.
