What is the role of HIF1α in creation of new blood cells

HIF1α binds with oxygen in the lung, this stimulates the production of erythropoietin

HIF1α binds with oxygen in the lung, this inhibits the production of erythropoietin

HIF1α binds with oxygen in the kidney, this stimulates the production of erythropoietin

HIF1α binds with oxygen in the kidney, this inhibits the production of erythropoietin

In regards to the relationship between haemoglobin and oxygen, what does the term 'cooperative binding' mean?

The first bound oxygen molecule attaching to heme increases the affinity for subsequent molecules to bind also

Due to the nature of the porphryn ring in haemaglobin, oxygen is the preferred binding molecule. The iron of the porphryn ring and the oxygen molecules demonstrate a 'cooperative' relationship

Cooperative binding is the term used to describe the passive exchange within haemaglobin between oxygen and carbon dioxide

In haemaglobin, cooperative binding refers to the ease in which oxygen can be both bound and released

In patients suffering typical Iron Deficiency Anaemia, what would an expected mean corpuscular volume be

Below 80fL

80 to 100fL

Above 100fL

Iron Deficiency Anaemia would not affect mean corpuscular volume

What is the name of the protein that allows safe storage of iron within cells?

Ferrous Reductase

Transferrin

Hepcidin

Ferritin

How does TNFα contribute to anemia in Anaemia of Chronic Disease?

Blocks the uptake of erythropoietin by bone marrow

Stimulates the proliferation of meglaoblasts

Inhibits the production of erythropoetin from the kidney

Prevents iron absorbtion in the duodenum

What is the role of haptocorrin in B12 absorbtion

Stimulares the production of Intrinsic Factor in the stomach

Prevents digestion in the stomach

Prevents digestion during transfer through the small bowel

Cleaves B12 from Intrinsic Factor prior to absorbtion in the small bowel
