Presentation transcript:

 Determine the number of protons, neutrons and electrons in each of the following  Fluorine-20  Helium-4  Which of those compounds is an isotope?

 Define:  Cohesion  Adhesion  pH  Describe 4 reasons why water is a versatile molecule that is important to living beings  Stomach acid has a pH of 2 and ocean water has a pH of 8  Which one is acidic?  Which one is closer to being neutral?

 Fill in the chart with the missing vocabulary terms  Define:  Ions  Chemical bond  Macromolecule  Polymer  Give examples of monosaccharides, disaccharides, and polysaccharides

 Name what each is made of and a use for each:  Carbohydrate  Lipid  What is the difference between a saturated and unsaturated fat?

 Proteins are complex. Describe how they form their complex structure.  In a chemical reaction, what exactly happens to the atoms?  What are 4 functions of a protein?  What does it mean to denature a protein and what cause to happen to that protein?  How are enzymes helpful to living organisms?

 Macromolecules  Polymer  Monomer  Carbohydrate  Polysaccharide  Disaccharide  Monosaccharide  Lipid  Glycerol and fatty acid  Saturated  Unsaturated  Protein  Enzyme  Catalyst  Amino acid  Denature  pH  Acid  Base  Neutral  Nucleic acid  Nucleotide  Chemical bond  Hydrogen  Ionic  Covalent  Chemical reaction  Activation energy  Valence electrons  Atom  Molecule  Proton, neutron, electron  Ion  Isotope  Water  Cohesion  Adhesion  Surface tension  Capillary action  Polarity  Solution
