How do Fibrinogens clot wounds?
- Starts soluble
- Turns into insoluble fibrin
- Forms a clot at wound
What are albumins?
- Smallest plasma protein

- Bind insoluble metabolites as transport proteins
What are Globulins?
- Antibodies
2. Main dissolved proteins in plasma
What are the three plasma proteins?

- Globulins
RBC’s are 7-8 micrometer __________ disks
biconcave disks. Uniform shape and size
Are RBC’s mitotic?
nooooope
RBC’s are highly elastic due to ________
Spectrin
Are RBC’s easily deformed?
hell yeah

120
What are key proteins associated with Spectrin?
- Glycophorin
2. Anion transporter channel (band 3)
Glycophorin is a ______ channel and ______ dimer. It attaches to ____ and _____ dimer as well as stabilizes _____ tetramers
Glycophorin is a transport channel and glyprotein dimer. It attaches to actin and spectrin dimers as well as stabilizes spectrin tetramers
The anion transporter channel is a ______ protein that attaches to spectrin via ______. Allows HCO3 to cross plasma membrane in exchange for ___ which releases _____ in the lung.
The anion transporter channel is a glyportein protein that attaches to spectrin via Ankryin. Allows HCO3 to cross plasma mebmbrane in exchange for Cl which releases carbon dioxide in the lung.
