Many Scientists Use Chemical Inhibitors to Interfere with Normal Signaling

question 109

Multiple Choice

Many scientists use chemical inhibitors to interfere with normal signaling pathways within eukaryotic cells. If such inhibitors are large, nonpolar molecules, what is the likely method of action of these chemical inhibitors?

• A)These chemical inhibitors likely enter eukaryotic cells and interfere with components of the signal transduction pathway.
• B)These chemical inhibitors likely enter the nucleus and prevent the transcription of the pathway of interest's target genes.
• C)These chemical inhibitors likely bind to receptors and interfere with receptor activation or signal-receptor binding.
• D)These chemical inhibitors likely interfere with the termination of signaling, so eukaryotic cells can't process new signals.
