What is active transport?
What are the three major classes of transport systems in prokaryotes?
- Simple transport
- Group translocation
- ABC transporting systems
Of which three componets consists the ABC transport system?
- Substrate-binding protein
- Transmembrane transporter
- ATP-hydrolizing protein
- Higher grades + faster learning
- Never study anything twice

What is the name of the reaction where a solute and a proton are cotransported in one direction?
What is the name of the reaction where a solute and a proton are transported in opposite directions?
In which ways does group translocation differ from a simple transport reaction?
- The transported substance is chemically modified during the transport process.
- An energy-rich organic compound drives the transport event.
What does the phosphotransferase system do?
