Enzymes, Dehydration Synthesis, and Hydrolysis

Video 1: Enzyme video from class

Video 2: Enzymes
                            However he is using substrate as both a reactants (what going into a chemical
                            reaction) and how we talked about substrate in class (the definition you need to
                            know). We call a substrate the object that is going into an enzyme that is going to be
                            broken apart by (Hydrolysis) or put together by Dehydration Synthesis.

Hydrolysis & Dehydration Synthesis

Macromolecules

Macromolecules:     
                                 All Macromolecules

                             The following are longer videos about each type of macromolecule but are useful!
                                  Lipids
                                  Carbohydrates
                                  Protein
                                  Nucleic Acid

Disclaimer: unfortunately these videos are longer then what I would have liked however they are very helpful in understanding the information.

pH Scale

Class Video 1: pH, acids and bases

Class Video 2: Cancer and pH

Website Link (that we talked about in class): pH and respiration

Additional video: pH Scale

Characteristics of Life

Link #1: Website about the characteristics of life with some pictures

Link #2: GREAT STUDY TOOL! Has videos, practice, and reading

Properties of Water Lab

Watching videos = lab & assessments will be easier

Polarity ~ 4 minutes

Hydrophobic vs Hydrophilic:  Definition ~ little over 3 minutes
                                                     Example ~ 3 minutes
              
Adhesion, Cohesion, Surface Tension  ~ 2 minutes

Videos that answer questions to the lab:
   Part 1:  Why is water a good solvent?
   Part 2:  Adhesion, Cohesion, and Surface tension (talks about penny example)
   Part 4: Pic below
