Calcium pumps differ from sodium-potassium pumps in that
A) they do not require energy in order to operate.
B) they are rarely found in the central nervous system.
C) while moving one type of ion out of the cell,they do not move another type of ion into the cell.
D) they are not essential for the healthy operation of the nervous system.

Question

Quizplus · Accepted Answer

Calcium pumps move calcium ions out of the cell without moving any other type of ions into the cell. This is different from sodium-potassium pumps, which move sodium ions out of the cell and potassium ions into the cell. Calcium pumps do require energy to operate and are important for many physiological processes, including muscle contraction, neurotransmitter release, and cell signaling. While they may not be as prevalent in the central nervous system as in other tissues, they are still essential for the healthy operation of the nervous system. Therefore, options A, B, and D are incorrect.
