Question

Quizplus · Accepted Answer

The process of accumulating amino acids and sugars in animal cells involves coupled transport. Coupled transport, also called secondary active transport, uses the energy stored in an ion concentration gradient to transport solutes across a membrane. In this process, the movement of one solute (usually an ion) down its concentration gradient drives the movement of another solute (such as an amino acid or sugar) against its concentration gradient. This process requires the presence of a symporter or antiporter protein in the membrane. ATP pumps, sodium-potassium pumps, glucose pumps, and proton pumps all involve primary active transport, which directly uses ATP to transport solutes across a membrane.
