- a = glycerol + fatty acid.
are another source of energy but some may contribute to heart disease. Most plant __ are unsaturated oils and most animal __ are saturated.
- b small nitrogen containing molecules, amino acids, are joined to form dipeptides which are joined to form polypeptides which may be joined to other polypeptides to from proteins. Proteins have unique 3 dimensional shapes or configurations that enable them to function as enzymes to catalyze reactions and function in other active ways.
- c =Mass number=protons+ neutrons
- d Primary structure = sequence of amino acids
Secondary structure = coiling to form an alpha helix or folding to form a pleated sheet - hydrogen bonding may be involved
Tertiary structure - Overall, 3 - D shape, usually described as fibrous or globular
Quaternary structure - many proteins have multiple peptide chains or subunits - how these fit together is called quaternary structure
- e receives packages such as transport vesicles on one side, modifies products, then repackages in new transport vesicles for other sites

5 True/False Questions
cytoskeleton → ibers that run through the cell providing support, movement, anchorage and movement of organelles, 3 types - microfilaments, intermediate filaments, microtubules - the microtubule organizing center is called the centriole
Ionic bonds → strong bonds where atoms share electrons - two or more atoms held together by a covalent bond are called a molecule
functional groups → some atoms lose or gain electrons to form ions. attraction between ions of opposite charge form ionic bonds
Vacuoles (Eukaryotic cells) → houses chromosomes (DNA + chromatin - protein), and nucleolus - site of ribosome parts assembly, in an membrane = nuclear envelope
Nucleus (Eukaryotic cells) → houses chromosomes (DNA + chromatin - protein), and nucleolus - site of ribosome parts assembly, in an membrane = nuclear envelope
