Question

For Na* to be sequestered in a vacuole, there must be a proton gradient between the cytoplasm and the vacuole. How does a proton gradient between the cytoplasm and the vacuole contribute to the sequestration of Na*? A. The proton gradient between the cytoplasm and vacuole provides the energy needed to pump potassium ions (K) away from Na". The pumping of K occurs prior to Na B. The proton gradient between the cytoplasm and vacuole provides the energy used by C. The proton gradient is needed for the activation of enzymes that detoxify Na* prior to its D. The proton gradient between the cytoplasm and vacuole is used to create the ATP E. The proton gradient between the cytoplasm and vacuole provides the energy used by sequestration. Na H antiport proteins that sequester Na* in the vacuole sequestration. consumed during the active transport of Na". proton pumps (H-ATPase proteins) that sequester Na" in the vacuole

Explanation / Answer

Answer is B.

The proton gradient between the cytoplasm and vacuole provides the energy used by Na+/H+ antiport proteins that sequester Na+ in the vacuole.

This energy is provided by proton gradients H+-ATPase.
