Signal Transmission and Gene Expression

Budding scientists learn about signal transmission, exploring intercellular and intracellular chemical movements. The instructor shows how epinephrine signals other chemicals in the body and can cause our DNA to express different proteins.

Instructional Ideas

  • Pause video around 6:20 to allow scholars to ask questions, discuss signal transduction, and record notes on epinephrine
  • Repeat this process after discussion on gene expression
Classroom Considerations

  • Must have a computer, access to the Internet, and a way to project the video to use the resource
  • Video assumes your class knows enzymes and ATP; also expects they have a basic foundation for a signal transduction pathway
  • Video 26 in a series of 31

  • Includes a link for a concept map, slideshow, and review sheet
  • Provides links for related videos near the end

  • Although the instructor attempts to simplify signal transduction, this is a complex process which may overwhelm some pupils
