Cell to cell communication
Introductory 100 level biology class
Non-majors
Christine Andrews, Katie Morrison-Graham, Bianca
Breland
, Marilyn Thomas,
Sarah Cabbage, Kat Milligan-
MyhreSlide2
Goals
Understand how cells communicate and pass on information
Appreciate the importance of cell-cell communication to drug activities and response to the environment
Objectives
Describe and diagram a process by which cells communicate
Predict the cause or consequence of alterations in cell communication and justify your answerSlide3
Summative Assessment on an exam
Ask students to draw or identify components of a signaling pathway
We will provide a scenario (s) and ask students to: Identify if an agonist or antagonist is described
Predict effect on cell and/or whole organismSlide4
Class prep work
Multiple questions about readingsSlide5
Scenario
It’s a dark and stormy night… You are walking home alone and you hear a rustle in the bushes. What do you feel? What is happening in your body?Slide6
Fight or Flight ResponseSlide7
Cell communication review
Organize strips in envelope #1 in proper order for cell-cell communication
2 minutesCheck and discuss order of stripsSlide8

What is the main signaling molecule for fight or flight response?Slide13
What would an
antagonist of epinephrine do to your heart rate? (TPS) Slide14
Can you think of a reason you would like to take an antagonist for this? (TPS)Slide15
Brainstorm: What other examples of cell-cell communication can you think of?
Goal is to reinforce that there are multiple examples of cell – cell communication in the body.Slide16
