Verified step by step guidance

Understand the concept of active transport: Active transport is a process that moves molecules across a cell membrane against their concentration gradient, requiring energy input.

Differentiate between primary and secondary active transport: Primary active transport directly uses ATP to transport molecules, while secondary active transport relies on the energy from the concentration gradient established by primary active transport.

Recognize the role of ATP in primary active transport: In primary active transport, ATP is used to change the shape of the transport protein, allowing molecules to move against their concentration gradient.

Identify the mechanism of secondary active transport: Secondary active transport uses the energy from the concentration gradient created by primary active transport to move additional molecules, often involving a symporter or antiporter.

Connect the relationship between the two: Secondary active transport depends on the concentration gradient established by primary active transport, making them interrelated processes in cellular transport.
