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.

The same second messengers are used in many different cells, but the response to second messengers is different in each cell. How is this possible?

What would happen if the intracellular domain of a cellsurface receptor was switched with the domain from another receptor?

How does NF-κB induce gene expression?

a. A small, hydrophobic ligand binds to NF-κB, activating it.

b. Phosphorylation of the inhibitor Iκ-B dissociates the complex between it and NF-κB, and allows NF- κB to enter the nucleus and stimulate transcription.

c. NF-κB is phosphorylated and is then free to enter the nucleus and bind DNA.

d. NF-κB is a kinase that phosphorylates a transcription factor that binds DNA and promotes protein production.

A scientist observes a mutation in the transmembrane region of EGFR that eliminates its ability to be stabilized by binding interactions during dimerization after ligand binding. Which hypothesis regarding the effect of this mutation on EGF signaling is most likely to be correct?

a. EGF signaling cascades would be active for longer in the cell.

b. EGF signaling cascades would be active for a shorter period of time in the cell.

c. EGF signaling cascades would not occur.

d. EGF signaling would be unaffected.

A scientist notices that a cancer cell line fails to die when he adds an inducer of apoptosis to his culture of cells. Which hypothesis could explain why the cells fail to die?

a. The cells have a mutation that prevents the initiation of apoptosis signaling.

b. The cells have lost expression of the receptor for the apoptosis-inducing ligand.

c. The cells overexpress a growth factor pathway that inhibits apoptosis.

d. All of the above.
