How do large molecules move down the concentration gradient?

How do large molecules move down the concentration gradient?

Large molecules such as glucose move down the concentration gradient with the help of proteins facilitated diffusion Diffusion of water molecules through the cell membrane down (with) the concentration gradient osmosis Movement of substances against the concentration gradient; requires energy

How do molecules move across the lipid bilayer?

Nonpolar molecules (ex: CO2 & O2) move across the lipid bilayer down the concentration gradient diffusion Large molecules such as glucose move down the concentration gradient with the help of proteins facilitated diffusion Diffusion of water molecules through the cell membrane down (with) the concentration gradient

What is the process by which a cell surrounds and takes in?

Process by which a cell surrounds and takes in material from its environment endocytosis Process by which a cell surrounds and removes materials from inside the cell exocytosis Movement of substances across the cell membrane from high concentration to low concentration

Which type of Transport requires energy to move substances across membrane?

Which type of transport requires energy to move substances across the cell membrane? active transport Nonpolar molecules (ex: CO2 & O2) move across the lipid bilayer down the concentration gradient diffusion Large molecules such as glucose move down the concentration gradient with the help of proteins facilitated diffusion

What type of molecules can pass through simple diffusion?

Molecules That Pass Through Simple Diffusion: Only small molecules can pass through simple diffusions, such as H2O, O2, and CO2. Osmosis: Osmosis is the passive movement of water molecules from an area with a low solute concentration to one that has a high solute concentration through a membrane that is semipermeable.
