Crash Course Biology #7: In which Hank does some push ups for science and describes the "economy" of cellular respiration and the various processes whereby our bodies create energy in the form of ATP.

By Paul Andersen:

Paul Andersen covers the processes of aerobic and anaerobic cellular respiration. He starts with a brief description of the two processes. He then describes the important parts of the mitochondria. He explains how energy is transferred to ATP through the processes of glycolysis, the Kreb cycle and the Electron Transport Chain. He also explains how organisms use both lactic acid and alcoholic fermentation.

By Paul Andersen:

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.

Part I:

Things You Should Make Sure You Understand:

  • The energy processing strategies of each of the following modes of nutrition, and example organisms that engage in each mode:

    • Heterotrophs

    • Photosynthetic Autotrophs

    • Chemosynthetic Autotrophs

  • Why food molecules need to be broken down into smaller molecules for energy to be harvested from them.

  • The molecule that is oxidized and the molecule that is reduced in any REDOX reaction.

  • The starting materials, end products and eventual fates of all of the molecules used and produced in glycolysis, lactic acid fermentation and ethanol fermentation.

Part II:

Things You Should Make Sure You Understand:

  • The starting materials, end products, and eventual fates of all of the molecules used and produced in the acetyl-coA cycle, the Kreb’s cycle and oxidative phosphorylation.

  • The relationship between the evolution of photosynthesis, the evolution of oxidative phosphorylation, and the evolution of multi-cellular life.

  • The meaning of the term “proton-motive force”.

  • The relationship between the catabolic pathways of cellular respiration and the anabolic pathways of biosynthesis.
