Agenda  Biomolecules Review Practice questions  What is in my food?? Lab  Baggie Stations (or Kahoot)  Exit Ticket

Carbohydrate  Sugar or starch  Monosaccharide and polysaccharide  Energy and structure  Examples: Glycogen, starch, cellulose, glucose  Related organelles: Mitochondria: uses carbohydrates (sugar) to make energy Chloroplast: uses CO 2 and sunlight to make carbohydrates

Lipid  Fats, oils, and waxes  Glycerol and fatty acids  Form boundaries (makes up the cell membrane), insulation, and protection  Examples:  lard  vegetable oil  Fats  Organelle:  Cell membrane

Protein  Meat, fish, nuts, enzymes, and polypeptides  Amino Acid  FUNCTION OF THE PROTEIN CHNAGES WHEN THE ORDER OF THE AMINO ACIDS CHANGE  Does the work of the cell, speeds up chemical reactions (enzymes), and builds muscles  Examples:  Enzymes  Hemoglobin  insulin  Organelle:  Ribosome

Nucleic Acid  DNA and RNA  Nucleic Acids Nitrogenous bases Adenine Thymine Guanine Cytosine  Carries genetic information and helps in protein synthesis (protein making)  Organelle:  NUCLEUS

What is in my food?? TESTING BIOMOLECULES  4 students per group  Each group test for starch, sugar, lipids, and proteins  FOLLOW THE LAB PROCEDURE CAREFULLY Sugar = Benedicts = yes if turns color Starch = Iodine = yes if blueish-black color Protein = Biuret = yes if blue-purple color Lipid = paper bag = yes if oil stain  CLEAN-UP without throwing away test tubes  CLASS DEBRIEF TOMORROW

WHAT STUCK WITH YOU? EXIT TICKET

CARBOHYDRATES  AKA: Sugar, polysaccharide, glucose  Monomer: Monosaccharide  Function: Storage of energy and provide structure  Examples: glycogen, starch, cellulose, glucose (suffix ‘ose’)  Related organelles: Mitochondria uses carbohydrates (sugar) to make energy Chloroplast: uses CO 2 and sunlight to make carbohydrates (sugar)

NUCLEIC ACIDS  AKA: DNA, RNA  Monomer: Nucleotide Adenine Thymine/Uracile Cytosine Guanine  Function: carry genetic information, protein synthesis  Examples: DNA, RNA  Related organelles: Nucleus (control center of the cell)

LIPIDS  AKA: Fats, Oils, Waxes  Monomer: Fatty Acid and glycerol  Function: form boundaries (makes up the cell membrane!); insulation; protection  Examples: lard, vegetable oil, fats  Related organelle: cell/plasma membrane HYDROPHOBIC = INSOLUABLE = DOES NOT DISSOLVE IN WATER

PROTEINS  AKA: enzyme, polypeptide  Monomer: Amino Acid Protein is what the ORDER of the amino acids are  Function: Do ALL work of the cell  Examples: enzymes, catalysts, lactase, hemoglobin, insulin (suffix ‘ase’)  Related organelles: RIBOSOME (location where proteins are made)
