Active Transport •Movement of molecules up the
concentration gradient.•Requires energy•Carrier proteins can also serve as
“pumps” during active transport.

•The membrane proteins are very specific. One protein that moves glucose will not move calcium.
• Sodium Potassium Pump – works to maintain a higher concentration of sodium (Na) ions inside the cell and a higher concentration of postassium (K) ions outside the cell. • Requires energy to do so.• Creates and electrical gradient across the
cell membrane which is essential for nerve impulses.
