    I learned more in this short video about enzymes than I've learned since taking BIO 210 beginning at the end of August. Thanks for all your videos! Very helpful

      Doris Zinna I can't agree you more. I've finals tomorrow and I can't believe my instructor did not explain as well as this clip.

    1. By reducing the energy required to start a chemical reaction
    2. Energy
    3. Because the energy is absorbed
    4. Because the energy is released
    5. Heat
    6. Substrate
    7. Active site

    1:17 Isn't it that energy is absorbed when bonds are broken rather than released?

    Thank you so much for making this video. So I am assuming live food has enzymes but once you cook the food you kill all the enzymes correct ?

    • @BeverlyBiology
      @BeverlyBiology  7 років тому +3

      I wouldn't say the enzymes are "killed". This implies enzymes are living organisms. It would be correct to say cooking "denatures" enzymes. This means the high heat destroys the molecule.

    What is the difference between locl and key theory and induced fit theory

    • @Haileerionda
      @Haileerionda 6 років тому +1

      lock and key is just enzyme & substrate. induced fit is when the enzyme wraps around the substrate to do a multitude of things to the product like make the enzyme more stable or just provide a more stable enviroment. I know you posted 7 months ago but answering this question is helping me learn or remember for myself . :)

  • @ScienceFan1859
    @ScienceFan1859 8 років тому

    You used a nuclear reaction as your example of chemical reaction. Chem reactions rearrange electron relationships (bonds) Nucleus unaffected. nuke reactions change element (change nucleus) H fused with H creates He in your example. rest of video is tight!

    • @BeverlyBiology
      @BeverlyBiology  8 років тому

      So let me guess something about your screen name... the 1859 is in reference to Darwin's book "On the Origin of Species by Means of Natural Selection." Am I correct?

    • @ScienceFan1859
      @ScienceFan1859 8 років тому

      Maybe you could find a graphic for decomposition of H2O2 into H2O + O2. thats a chem reaction. 1859? change the subject? Eschew obfuscation!
