Study Notes
Active Transport
- The main difference between primary and secondary active transport is the direct use of ATP energy: primary active transport directly uses ATP energy, whereas secondary active transport uses the energy generated by the primary active transport.
Primary Active Transport
- Primary active transport directly uses ATP energy to transport molecules across cell membranes.
Role of ATP
- ATP plays a crucial role in primary active transport, providing the energy required to transport molecules against their concentration gradient.
Secondary Active Transport
- Secondary active transport uses the energy generated by primary active transport to transport molecules across cell membranes.
Purpose of Secondary Active Transport
- The purpose of secondary active transport is to transport molecules across cell membranes, often using the energy generated by primary active transport.
Transport Against Concentration Gradient
- Active transport is the type of transport used to transport molecules against their concentration gradient.
