But not all active transport is the same. Scientists split it into two major types based on how that energy is used.
Let’s break them down. The Analogy: A personal bodyguard physically shoving someone through a VIP door. what are the two major types of active transport
In primary active transport, the cell uses energy from ATP to change the shape of a protein pump. This physical shove moves molecules across the membrane, often against their gradient. But not all active transport is the same
Energy (ATP) → Pump changes shape → Solute moves. Type 2: Secondary Active Transport (The Carpool Lane) The Analogy: A car using the momentum of a downhill roller coaster to pull a second car uphill. what are the two major types of active transport
