Some materials can move across the cell membrane against a concentration gradient by?

Answer 1

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.

Answer 2

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.

Answer 3

utilizing active transport mechanisms such as protein pumps or vesicle transport. These processes require the cell to expend energy in the form of ATP to move molecules or ions against their concentration gradient.

Answer 4

Molecules too large to be moved through the cell membrane can be transported into a cell by endocytosis.

Answer 5

Endocytosis.

Answer 6

active transport

Answer 7

passive transport
