What is active transport? Movement of molecules into or out of a cell down a concentration gradient Diffusion of molecules within a cell Rapid movement of molecules in a solution Movement of molecules into or out of a cell against a concentration gradient Movement of molecules into or out of a cell using special proteins and not requiring an expenditure of energy

Rahma took these notes on a process involving the movement of molecules, but she forgot to title them. -Causes molecules to move until they are evenly distributed -Moves from high concentration to low concentration -Has no need for added energy -Can occur with or without a membrane being present

Describe the movement of molecules in diffusion. Molecules are moving from a lower concentration to a higher concentration. Molecules are moving from a higher concentration to a lower concentration. Molecules are moving from a higher concentration to a lower concentration and then from a lower to higher concentration. Molecules are moving from a lower concentration to a higher concentration and then from a higher concentration to a lower concentration.
