Question

neurons are cells of the nervous system. as part of its normal function, a neuron pumps sodium ions (na+) out of the cell and potassium ions (k+) into the cell. which statement describes the role of active transport in this process? the process releases energy that is used to make atp. the process releases energy in the form of heat. the process requires energy that is provided by the sodium and potassium ions. the process requires energy that is provided by atp.

Explanation:

Active transport is an energy - requiring process. In neurons, the sodium - potassium pump uses energy in the form of ATP to pump sodium ions out of the cell and potassium ions into the cell. It does not release energy to make ATP, nor does it release energy in the form of heat, and the energy is not provided by sodium and potassium ions themselves.

Answer:

The process requires energy that is provided by ATP.
