 What happens during Active Transport? | • Cell used ATP to carry things across membrane • Requires carrier proteins |
| What are four types of Active Transport? | • Symport system • Anitport System • Primary active transport • Secondary active transport |
| What are two examples of primary active transport? | • calcium hydrogen pump • sodium potassium pump |
| What happens in the Symport system? | • two substances are moved across a membrane in the same direction |
| What happens in the Antiport system? | • two substances are moved across a membrane in opposite directions |
| What happens in the Primary active transport? | • Energy comes from hydrolysis of ATP |
| What happens during Secondary active transport? | • transport driven indirectly by energy stored in ionic gradients created by the operation of primary active transports |
| Types of Secondary Active Transport |  |
