    Included Quiz Questions

    1. CC
    2. C
    3. CXC
    4. CX3C
    5. CCL5
    1. C denotes a cysteine-cysteine bond, X denotes an amino acid between adjacent cysteine bonds.
    2. C denotes a carbon-carbon bond, X denotes an amino acid between adjacent carbon bonds.
    3. C denotes a cysteine-cysteine bond, X denotes a carbon between adjacent cysteine bonds.
    4. C denotes a cysteine-amino acid bond, X denotes an amino acid between adjacent cysteine-amino acid bonds.
    1. A 7 transmembrane receptor is linked to a G-protein complex which activates the cell, moving it towards the higher concentrations of chemokines.
    2. The chemokine receptor on the lymphocyte depolarizes rapidly, allowing for a more intense response in a higher concentration gradient.
    3. A 7 transmembrane receptor slows the response of the lymphocyte, moving it down the chemokine concentration gradient.
    4. The lymphocyte irreversibly attaches to chemokines and uses diffusion to move down the concentration gradient.
    5. The chemokines stimulate a transmembrane G protein in the lymphocytes, inactivating the cell.
