Quartenary Structure
- 2 alpha and beta chains -Fe containing heme group |
|
|
|
O binds to __?
CO2 binds to __? |
Fe
NH2 of the amino acids in the Polypeptide chain |
|
|
|
How many Fe atoms does a Hemoglobin molecule contain?
|

|
Has 2 alpha and 2 beta chains. Each chain contains an Fe atom.
|

Newborn (14-20 g/100ml)
|
|
|

|
What carries Hb
|
|
|
Give 3 diseases that result in LOW hemoglobin values in the blood?
|

Hyperthyroidism Cirrhosis of the liver |
|
|
|
Give 3 diseases that result in HIGH hemoglobin values in the blood?
|
Polycythemia
COPD (Chronic Obstructive Pulmonary Disease) Conjestive Hrt Failure |
|
|
|
Define and Give 2 examples of COPD?
Which of the examples is reversible? |
Chronic Lung Disease in which breathing is slowed or forced.
-Asthma (obstruction of air out of lungs) or Emphysema/Chronic Bronchitis (obstruction of air through the airways and out of lungs) Asthma is reversible |
|
|
|
What is polycythemia?
|
Abnormally large amounts of RBC is th blood
-Overgrown BM -Enlarged Spleen (breaks down RBC) -Abnormal increase in RBC's |
AKA: Erythremia
|
|
|
How do you treat Primary and Secondary Polycythemia?
|
Primary- Radiation Therapy, Take Blood Out of System (Phlebotomy), or chemotherapy w/ anti-metabolite drugs(cytoxan)
Secondary- depends of cause! Usually secondary polycythemia (increase in RBC) is the body is trying to compensate for loss of O, so your body will proudce more RBC's as a result to increase carring capacity to tissues. If this is the case you must replenish pt w/ O. |
