The first MWM Energy Metabolism lesson answers the question, why do we have to eat such an enormous amount of food?
The answer is to comply with the second law of thermodynamics. If you have a chemistry background, you should recognize this as a light review of the thermodynamics unit from a general chemistry class, with its most essential concepts teased out and packed into a half hour lesson. If you don’t, you can use this as a basic foundation for understanding the biochemistry to follow.
The lesson relates the 2nd law to food coloring dispersing in water, how a hydropower plant operates, ATP production, and why we need to eat our bodyweight in food more than once a month. In the process, we have a little fun.
