    G1
  11. what is done during the S phase
    protein synthesis and DNA synthesis
  12. gluconeogenesis occurs where
    • liver in cytoplasm
    • to a lesser extent the kidney
  13. breakdown product of fat metabolism
    acetyl CoA
  14. breakdown product of TAGs
    glycerol (which can be used in gluconeogenesis)
  15. smooth er does what
    • lipid and steroid synthesis
    • drug detox
  16. function of golgi apparatus
    modifies proteins with carbohydrates
  17. fate of proteins in golgi
    to cell membrane, then either secreted or targeted to the lysosome
  18. intermediate filaments
    • keratin
    • desmin (muscle)
    • vimentin (fibroblasts)
