Question

what process is being shown in the image?
a sodium potassium pump
b active transport
c isotonic solutions
d passive transport
part b
which statement best explains the answer to part a?
a a protein is carrying the molecule out of the cell
b energy is not being used to transport molecules into the cell
c a concentration gradient is being used to move the protein into the cell

Explanation:

For Part A, the sodium - potassium pump is a type of active transport. Active transport requires energy to move substances against their concentration gradient. Without seeing the image, if it shows a process where energy is used to move molecules, active transport is a likely answer. For Part B, in active transport, energy is used to move molecules. A protein carrier is often involved in active transport to move molecules across the cell membrane.

Answer:

Part A: B. Active transport
Part B: A. A protein is carrying the molecule out of the cell
