Chapter 9: Q. 26 (page 252)

Cells grown in the laboratory are mixed with a dye molecule that is unable to pass through the plasma membrane. If a ligand is added to the cells, observations show that the dye enters the cells. What type of receptor did the ligand bind to on the cell surface?

Short Answer

Expert verified

The ligand binds to Ion channel-linked receptor on the cell surface.

Step by step solution

01

Step 1. Introduction

Cells that are cultured in the laboratory were blended with a dye molecule. These molecules were unable to enter the cell. A ligand is added to the cell after some time it was noticed that a dye molecule enters the cells.

02

Step 2. Explanation

These ligands bind to ion channel-linked receptor which creates pores on the plasma membrane through which dye molecule cross the plasma membrane and enter the cell.

If a mutation in the associated G-protein鈥檚 alpha subunit prevented the hydrolysis of GTP how would the allergic response change? a. More severe allergic response compared to normal G-protein signaling. b. Less severe allergic response compared to normal G-protein signaling. c. No allergic response. d. No change compared to normal G-protein signaling.
