Answer:

B. It allows sodium and potassium to move against their concentration gradient

Explanation:

The role of sodium and potassium pump in the body is to help move ions against their concentration gradient. There are two types of transport (1) active transport (2) passive transport.

Passive transport is a natural phenomenon in which ions move from high concentration to lower concentration. In such transport no ATP/energy is required. In contrast to this, active transport is a kind of transport which occurs against concentration gradient and in order to facilitate this opposite movement of ions they require ATP/energy input. Sodium and potassium pumps perform active transport in our body. In neurons they play an important role of ion exchange. They move sodium and potassium ions against their concentration gradient for which they require ATP and thus help in basic functioning of neurons.

Answer:

A. All channel movement requires active transport to equalize the cell

Explanation:

Active transport is necessary for the sodium-potassium pump to work because all channel movement requires active transport to equalize the cell.

Answer:

The correct answer would be active transport by proteins.

When a molecule is transported against the concentration gradient it requires cellular energy and the process is termed as active transport.

The energy is either provided by the hydrolysis of the ATP (adenosine triphosphate) in primary active transport or by the electrochemical gradient in secondary active transport

Active transport takes place with the help of integral membrane proteins or transport proteins which form carriers or channels across the membrane.

Examples may include a sodium-potassium pump, uptake of glucose in small intestine et cetera.
