Question

Why is secondary active transport considered indirectly powered by primary active transport in the glucose active symporter model?

Accepted Answer

Because the sodium gradient established by the sodium-potassium pump provides the energy for glucose transport.

Answer

Because glucose is transported using the energy from potassium ions.

Answer

Because secondary active transport uses ATP directly.

Answer

Because secondary active transport does not require any form of energy.
