Learn how adrenaline works within our bodies to initiate the fight or flight response! This video illustrates the basic principles of signal transduction mechanisms mediated by membrane-bound receptors by focusing on how adrenaline works on a cellular level.

This video was created by Nathalie Launder, an undergraduate student at New York University Abu Dhabi, as part of an introductory biology course taught by Dr. Kristen Sadler Edepli (Associate Professor at NYU Abu Dhabi) and Mona Kalmouni (Associate Instructor at NYU Abu Dhabi). It is part of our "Student Sketches" series, featuring videos created by students in conjunction with university and high school courses.
