Video: ATP – Energy of the Cell

In this lecture, I deal with the concept of Energy, which is the ability to do work. I talk about ATP and how it is the energy currency of the body and about how it works. I also deal with a few people who have contributed a lot to what we now understand about the function of ATP and how energy is produced and stored in the body. It is part Chapter 9 in the textbook Biology: The Dynamics of Life, which is the chapter on Energy of the Cell.

  • Thank you! It’s always been Leslie’s fortΓ© explaining complicated stuff in such an easy way that can clearly be understood by many. Stay tuned because we’re adding new Biology videos to the site!

  • You have made energy of a cell so much easier to understand than my current professor. I wish I could take my classes from you instead, as I know I would pass without any problems. Thank you for making this resource available.

  • Really wish my professor would teach like this instead of like she’s speaking to a room full of doctors. Sigh. Thank you for the “easy to understand” information.

  • Thank you for explaining in a simple way. I understand know. All I got in my class was blah, blah,blah.

  • You’re a much better teacher than my professor! You break it down very well. Thanks for the post!!

  • THANK you!
    I’m studying for a Personal Trainer course and this is explained simply.
    I wish I had you years ago :).

  • OMG. Thank you very much. I have been an exercise science student for about
    a year and a half now and never understood ATP. Thank you for making this
    easy for me to understand. Thank you !thank you !thank you.!

  • I am currently a Paramedic major and cellular biology has been extremely rough this term. I found your videos and because of how easy you break things down I actually have a good shot at passing this class. I am excited to watch your A&P videos next term. Thank you for everything you are doing in the teaching world!
