Q

Immunoglobulin ____ is widely found in secretions and presents an antiseptic barrier which protects mucosal surfaces

18
Q

Immunoglobulin ____ is a surface receptor for B cells

19
Q

Immunoglobulin ___ is present only in trance amounts and acts to bind antigen and promote a release of vasoactive amines from mast cells

20
Q

Immunoglobulin ____ is the most common and freely crosses the placenta

21
Q

Immunoglobulin ___ is confined to intravascular space and helps eliminate circulating antigens and microorganisms

22
Q

The ___ _____ ______ is a non-specific response to inflammation, marked by alterations in levels of proteins

A

acute phase proteins

23
Q

The major fraction of O2 in the blood is complexed with ferrous proteins ______ and _______

A

hemoglobin and myoglobin

24
Q

Utilization of O2 generates ____ _____; involved in cell signaling and are capable of damaging cells

A

free radicals

25
__________ is involved with O2 transport and is located in RBCs; involved with O2 and CO2 exchange; is tetrameter with 2 α and 2 β globins; highly sensitive to pH, major buffer in blood
hemoglobin
26
______ is involved with O2 storage in cytoplasm specifically in skeletal, cardiac, and smooth muscles
myoglobin
27
______ _____ aid in the stabilization of globins; polar on the exterior and hydrophobic on the interior; basic help stabilize O2 binding
amino acids
28
______ increase the aqueous solubility of the otherwise poorly soluble hydrophobic heme group
globins
29
75% on ____ is attach to heme protein in the 2+ state; 15% is stored in the liver, spleen, and bone marrow ; predominantly reabsorbed in duodenum
iron
30
____ binding is cooperative; once it binds to one region it is then easier for the other regions to bind as well
O2
31
An ______ protein is a protein that exhibits changes in ligand (or substrate) affinity under the influence of small molecules; pH, CO2, 2,3-BPG example = hemoglobin
allosteric
32
Carbon dioxide has a much ________ affinity for hemoglobin than O2 and thus _________ the amount of O2 that can be transported
higher | reduces
33
True or False | There are few mutation in the genes encoding α-globin and β-globin polypeptides
False; there are over 900 documented mutations
34
A majority of the mutations in globins are _________
harmless
35
This disease is hereditary, caused by a single point mutation in β-globin (glutamic acid to valine), affects African populations, changing the structure of the RBC, the majority of symptoms being in early childhood.
sickle cell disease
36
``` Sickle cell disease is characterized by; intermittent episodes of _______ _______ chronic ______ of RBC painful _______ _______ ______ organ systems are affected ```
hemolytic anemia lysis vasocclusive crises (blood vessel blockage) multiple
37
True or False | Sickle cell disease can cause issues in the oral cavity
True; sickle cell disease can affect the mucosa (gingival enlargement, spontaneous hematoma, etc), can affect the teeth (delayed eruption, pulpal necrosis, etc), and more
38
True or False | More CO2 in the blood will cause hemoglobin to pick up more oxygen
False; since CO2 has a higher affinity for hemoglobin that O2, an increase in CO2 concentration will cause the hemoglobin to drop their O2; this is the BOHR effect
39
True or False | A increase in blood pH will cause hemoglobin to pick up more oxygen
True; hemoglobin would drop oxygen in a decrease in pH (more acidity) this is the BOHR effect
40
The ________ ______ states that hemoglobins oxygen affinity is inversely related to CO2 and pH. CO2 and pH are related an increase in CO2 (carbonic acid in blood) will decrease the pH
Bohr Effect
