Active Transport

What is the purpose of energy in active transport

To move molecules against their natural direction of movement, which requires ATP

What are the two types of active transport

Primary active transport and secondary active transport

What is primary active transport

ransport that directly uses ATP hydrolysis to move molecules against their gradient

Explain the sodium pump

pump 3 sodium (𝑁𝑎+) ions out of the cell and 2 potassium (𝐾+) ions into the cell

What is secondary active transport

ransport that uses the energy from another molecule moving down its gradient to move a second molecule against its gradient

What are protein pumps

Membrane proteins that use energy (ATP) to move specific solutes across the membrane

Draw and lable how active transport takes place
