Assume that an actively respiring cell has 3x number of

{\mathrm{K}^ + }

in its cytoplasm and 2x number of

{\mathrm{K}^ + }

entered into the cell. What is the process by which K⁺ transport has taken place?

View answer and explanation

Correct option: B

Secondary active transport

Option B (Secondary active transport) is correct because the cell already has a higher concentration of K+, and more K+ is entering, indicating transport against the concentration gradient, coupled with another ion's movement.
