  1. Programmed cell death occurs primarily by __________, where the cell _________, the cytoskeleton ____________ ____, the nuclear
    envelope ____________, and the chromatin _________ and fragments.
    • apoptosis
    • shrinks
    • breaks up
    • fragments
    • condenses
  2. During the final stage of apoptosis, the _______ ________ exhibits _____ and the cell surface is altered so that the cell is _______ before it breaks open.
    • plasma membrane
    • blebs
    • phagocytized
  3. During apoptosis, the cell surface becomes altered by ___________, and becomes transported to the outer monolayer; this acts as a “_____ _____” signal. Other signals act as “__ __ __” signals that have to be ______ or removed from the cell surface.
    • phosphatidylserine
    • "eat me"
    • "dont eat me"
    • inactivated
  4. Provide 3 examples of Apoptosis:
    • 1. Paw of a mouse fetus
    • 2. Tadpole tail
    • 3. Human epidermis
  5. Why are cells programmed to die?
    Because they are no longer needed.
  6. ___________ is cell death that is caused by physical or chemical injury, infection, or loss of blood supply. The cell in this type of cell death ______ and __________.
    • necrosis
    • swells and bursts open
  7. In __________ cells, apoptosis involves the action of proteases called _______. When active, they are named _________ where a large subunit, and a small subunit form 2 heterodimers. Activation proteases occur by_______ and are named ___________.
