013 - Free Energy Capture and Storage

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.

This is an excellent video. Paul has presented the material in a very organized manner. He went from simple information to complex information which can definitely be useful to not to scare the students.
