lipids
, b)proteins
, d)carbohydrates
phospholipids
proteins
cell recognition
-carbohydrates
,transport LARGE/charged molecules through the membrane
-proteins
,allow small molecules to pass through the membrane
-phospholipids
The cell membrane controls the movement of substances in and out of the cell
many molecules coming into the cell using a membrane vesicle (endocytosis)
small molecules crossing the lipid bilayer (diffusion)
They both involve the movement of molecules through proteins
Passive transport because the molecules are moving from high to low concentration
does NOT require energy
molecules move WITH the gradient
molecules move from high concentration to low
requires energy
molecules move AGAINST the gradient
molecules move from low concentration to high
Movement of water molecules from an area of high water concentration to an area of low water concentration
Requires energy (ATP!)
