013 - Photosynthesis and Respiration

Paul Andersen details the processes of photosynthesis and respiration in this video on free energy capture and storage. Autotrophs use the light reactions and the Calvin cycle to convert energy from the Sun into sugars. Autotrophs and heterotrophs use cellular respiration to convert this sugar into ATP. Both chemosynthesis and fermentation are discussed. The evolution of photosynthesis is also discussed.

Wow! Thanks for doing this!!! I teach AP Biology and for a variety of reasons (mostly sports injuries) several of my students missed almost the entire unit on energy transformations. I'm giving them links to your lectures to help them out .

So thanks from both me and my recovering students!
