Which of the following membrane proteins is responsible for

Which of the following membrane proteins is responsible for the passive movement of K^+ across the typical animal cell membrane? Select one: a. Transporter b. Receptor c. Channel d. Enzyme

Solution

The answer is Channel.. Channel are present in the plasma membrane which allows the movement of the ions inside and outside of the cell depending on the concentration gradient. It moves the ions from region of higher concentration to regions of lower concentration without using the cell energy. This is called passive movement..

Wheares other given options can also transport the ions against the concentration gradient..!!
