Bioenergetics

Paul Andersen introduces the concept of bioenergetics. He explains how living organisms utilize free energy in the Universe. He begins with a brief discussion of thermodynamics and Gibbs free energy. He then explains how reactions can be exergonic or endergonic. He also introduces the concepts of photosynthesis and cellular respiration.

Question: "Our brain is is constantly cashing in ATP". Do you mean that it consumes energy by converting ATP to ADP? Can you please elaborate?

[Savi]

I had to watch this for homework, great video!

[joshducote]

Your videos are very well explained and the examples are also incredibly helpful

[MohoBiechiz]

Didn't even come here for a class, yet I am interested.

That'''s interesting. Of course I am not quite sure how you might integrate that thinking with the energy fields around living and nonliving things (Kirlian photography and the communication between living things, per a book, The Life of Trees), and house spirits (The Adventures of a Brownie), and Children's Past Lives.

Thanks so much!!! I have a huge test on this tomorrow and I'm so scared :c

why would someone say that evolution violates the 2nd law of thermodynamics? In both cases things go from simple to complex.
