  1. there are two types of cells. Name and describe them
    • prokaryotic cell: does not have a nucleus and lacks membrane bound organelle
    • eukaryotic cell: contains a nucleus with complex membrane bound organelles
  2. what causes cellular diversity

  3. what is progeria and the cause
    • premature aging of the musculoskeletal and cardiovascular system.

  9. what is the function of receptor molecules and give an example
    membrane proteins that have an exposed receptor site where specific ligands attach and act in intercellular communication
  10. describe the causes, symtpoms and chromosome number of familial hypercholesterolemia (FM)

  17. what is transcription and where does it occur
    • occurs within euchromatin within the nucleus.
    • where pre-RNA is created in the DNA template.
  18. what is the central dogma of biology
    • the procedures of protien synthesis from dna
    • DNA--> RNA --> proteins
  19. what is translation and where does it occur
    occurs within the cytosol/cytoplasm where mRNA creates proteins via free ribsomes.
  20. describe the cytosol and its function
    • a semi liquid gel like substances that suspends all organelles
    • forms the enzymatic regulation and storage of fat vesicles
  21. describe the characteristics of mitochondrion and function
    • double membrane organelle
    • has its own circular DNA
    • site of ATP sythesis
    • formed from endosymbiosis
  22. describe the symptoms and cause of leigh's disease
  23. apoptosis
    • cell death that is part of normal development
    • presence of macrophages
  24. necrosis
    • cell death in response to trauma. 
    • Cells release their their contents because of cell rupturing. 
    • resulting in inflammation.
  25. How many total liters of blood is there in the body?
    5 liters
  26. What is plasma
    liquid portion of blood containing coagulants and everything except RBC
  27. descibre how RBCs biconcave shape iss significant
    contributes to RBC deformabiltiy, allowing it to move around in very thin environments such as capillaries.
  28. define microcytosis
    cells less than 8 microns
  29. define macrocytosis
    cells greater than 8 microns
  30. What would the presence of a lot of nucleated cells indicate in the blood
    immaturity of RBC would indicate hemolysis or acute hemolysis. usually the bone marrow pumps out immature cells in order to compensate for the loss of mature RBCs
  31. name the 5 different classes of white blood cells in the blood
    • neutrophils
    • lymphocytes
    • monocytes
    • eosinonphils
    • basophils
  32. what are indices
    certain values that are obtained from blood cell measurments
  33. what does hematocrit measure
    • volume of RBC in the blood.
    • directly related to the amount of hemoglobin the the blood
  34. rule of three
    • red blood cell count x 3 = hemoglobin value
    • hemoglobin value x 3 = hematocrit
  35. whatif there is a discrpency in rule of three
    hemolysis
  36. what is the normal value of hematocrit
    45%
