Question

several techniques are used to assess iron status. match each of the following terms with its definition.

1. major storage form of iron: (click to select)
2. transport protein for iron in (click to select) ferritin click to select)
3. membrane - bound protein th transferrin (click to select)
4. ratio of blood transferrin re transferrin receptor lick to select)

total body iron

Explanation:

1. The major storage form of iron is Ferritin. Ferritin stores iron in cells.
2. The transport protein for iron in the blood is Transferrin. Transferrin carries iron in the bloodstream.
3. The membrane - bound protein that binds iron - carrying transferrin is Transferrin receptor. It helps in the uptake of iron by cells.
4. The ratio of blood transferrin receptors to ferritin is related to Total body iron assessment, but for the matching:

• Term 1 (Major storage form of iron) matches Ferritin.
• Term 2 (Transport protein for iron) matches Transferrin.
• Term 3 (Membrane - bound protein) matches Transferrin receptor.
• Term 4 (Ratio related to iron) would be related to Total body iron, but for the first three terms, the matches are as above.

Answer:

1. Major storage form of iron: Ferritin
2. Transport protein for iron in blood: Transferrin
3. Membrane - bound protein (binds transferrin): Transferrin receptor
4. Ratio of blood transferrin receptors to ferritin (related to): Total body iron
