You get to reveal the ways in which cells use the energy stored in sugar to produce the ATP that powers their chemical reactions. View each of the major pathways involved in ATP production, and then see how this compares to photosynthesis.
After completing this tutorial, you will be able to complete the following:
What are the two types of respiration?
~ The two types of respiration are fermentation and cellular respiration.
How are fermentation and cellular respiration alike?
~ Fermentation and cellular respiration are alike in that they both begin with a series of reactions known as glycolysis, which breaks glucose molecules into smaller pyruvate molecules. They are also similar in that during both processes, ATP is produced for the cell to use.
How are fermentation and cellular respiration different?
~ Fermentation and cellular respiration differ in that fermentation does not require oxygen while cellular respiration does. Fermentation and cellular respiration are also different because water molecules are not produced during fermentation but are produced during cellular respiration. All fermentation reactions occur in the cell's cytoplasm but during cellular respiration, only glycolysis occurs in the cytoplasm. Lastly, fermentation produces a net gain of 2 ATPs while cellular respiration produces a net gain of 32 ATPs.
What causes muscle pain in our bodies after we exert ourselves?
~ As we exert ourselves, our cells may begin to run out of oxygen. As a result, our cells begin fermentation, which allows them to continue to produce ATP. This results in the production of lactic acid in our muscle cells. The accumulation of lactic acid is what causes muscle tenderness.
